1.0 OBJECTIVES:
Railway Board vide their minutes of the meeting for “Review of IOH/ POH
periodicity of coaches and performance review of LHB coaches” held in
Railway Board on 06.03.2014, No. 2007/M©/141/1 dated 12.03.14 under
item “B” and S. No. 14 for performance review of LHB coaches and other
issues directed CAMTECH to evolve a design of pit line with pre-fab.
constructions for expeditious implementation of projects. In addition to this,
need to construct a catwalk should also be re-examined as pit lines without
catwalks also have advantages of more open space, easy and speedy
construction and are economical as well. This hand book is prepared to cater
all the requirements of coaching depots.
2.0 NEW DESIGN OF PRE-FABRICATED PITLINE WITHOUT
CATWALK AND WITH ACWP (AUTOMATIC COACH WASHING
PLANT
Previously a 3Tier system for coach maintenance was adopted by Indian
Railway on the basis of recommendations made by CAMTECH and
approved by Railway Board vide their letter No. 95/M©/165/11 dated
09.08.1999. In three tier system, the provision of catwalk was made for
washing/ cleaning operation of coaches during maintenance. During
finalisation of report, the provision of automatic coach washing plants at
maintenance depot was examined but, at that time, Indian Railways were
still in the process of laying these plants at few locations. It was decided
that as Railways as become fully confident with their design, performance
and sources of supply and automatic plants get proven in service, the above
arrangement may be reviewed suitably in order to explore the possibility of
having pit lines without catwalks.
In catwalk less design, for changing destination boards and window glass
cleaning, adequate number of movable trolleys/forklifts with suitable
attachment may be required. The requirement of water pipeline for coach
washing may also be reviewed in such cases.
As discussed in 12th CMG at Guwahati & CME‟s conference at Mumbai
and Shimla, it is felt by some of the Railways that the activities to be carried
out on a catwalk can be undertaken with the help of alternative means such
as mobile platforms, listers etc and therefore pit line design should be
without cat walk.
During the seminar at CAMTECH on 21.07.2014 on the issue, participants
were of the opinion that catwalk contributes little but only makes hindrance
in the free movement of man and material. Daylight is restricted and layout
CAMTECH/2014/M/MFCD/1.0 2
Hand Book on maintenance facilities in coaching depot on IR November - 2014
makes clumsy. A new design of pit line without catwalk should, therefore,
be developed or Prefab casted catwalk with longer span may be provided.
Automated Coach Washing Plant
ACWP has been considered necessary for outside cleaning of the coaches.
This will reduce the efforts and time taken at the pitline considerably. It
will also improve the quality of the cleaning of the coaches. This will
ensure reduction in water consumption and wetness in the pitline. It has
been noticed that coach washing plants which are in use on Indian Railways
are not working properly due to various reasons. It is, therefore, proposed
that a washing plant of a specification equivalent to one available at
DMRC/PA coaching depots should be provided.
Unified Maintenance Pit-line
A unified pitline for internal cleaning of coaches/examination and repair has
been considered in place of separate facilities for internal cleaning of
coaches and repair/examination of coaches. It has been noticed that if
separate facilities are provided, the time taken in shunting is 1-2 hours and
thus the cycle time increases considerably. The very purpose of this
exercise i.e. to reduce the maintenance time gets defeated. Further, since
ACWP has been provided, the coach washing will anyway be done at the
entry point of the pitline, therefore, spillage of water on pitline will be
reduced to a great extent. This will serve the purpose of keeping the pit dry
to a great extent.
2.1 Merits and Demerits of Catwalk
SN Disadvantages of Catwalk Advantages of without Catwalk
01 Clumsy lay out Less clumsy lay out
02 Day Light is restricted Plenty of daylight id available
03 Cross movement is also
restricted
Easy movement of maintenance

2.2 Covered Shed
The coaching stock examination pattern in recent years has been changed
considerably resulting into extensive utilization of coaches. A rake once
turned out from a pit line will be examined after 3500 Kms and on round
trip basis, there can not be any compromise on quality of examination and
repairs. Extreme weather conditions like heavy rains etc will make it
difficult for the staff to do a quality job in time provided for examination.
Therefore a all weather covered shed has been provided. This will ensure
proper working conditions to the staff throughout the year and will save the
staff and the stock from the vagaries of weather. In this respect comparison
was made with the existing design of structure vis-à-vis pre-engineered
buildings. It has been noticed that the pre-engineered buildings have
following features:-
Simple design and light foundations
Standard component connections
Short learning curves
Fast and standardized erection process
Low weight flexible frames offer higher resistance to seismic forces
Future expansion is simple, easy and cost effective
Lighter structure weight
The cost of pre-engineered buildings is also less in compared to conventional
design buildings, therefore pre-engineered buildings have been recommended.
2.3 Views of Railways have been considered for provision of catwalks.
Railways are sharply divided on view of this facility. While E.Rly,
S.E.Rly. strictly feels that a catwalk is must, W.Rly. and C.Rly. are of the opinion
that catwalk is not required and work can be managed with portable lifting
platform. Views of other railways were also taken.
One more design has also been evolved by CAMTECH where catwalk can be
provided only at one side of the each pit and central bay can be left for movement
of the lifting platform.
As discussed in 12th CMG at Guwahati & CME‟s conference at Mumbai and
Shimla, it is felt by some of the Railways that the activities to be carried out on a
catwalk can be undertaken with the help of alternative means such as mobile
platforms, listers etc and therefore pit line design should be without cat walk.
However some other Railways were of the view that these activities can not be
CAMTECH/2014/M/MFCD/1.0 4
Hand Book on maintenance facilities in coaching depot on IR November - 2014
done properly without catwalk. The issue has been deliberated in detail. It is
proposed that Railways can have option from the two designs i.e.
i) No catwalk on either side
ii) Catwalk only on one side of pit line and area between two pit lines
should be without catwalk for free movement of man and material.
The details of these two designs are as per CAMTECH sketch no.3
and 4.
3.0 Twin depth pit
In the existing pit, staff can not walk without bending. Therefore, to avoid
this difficulty, it has been proposed to provide twin pit. In this design a pit
of size 600 mm wide and 450 mm deep pit has been provided in centre of
the main pit for easy walking of the staff. This will also serve as drain to
the pit as a FRP/Metallic mesh has been provided as a covered on the deep
drain for this purpose.
4.0 Modern Equipments
To improve reliability, reduce maintenance time and to have state of art,
facilities for examination, repair and maintenance of coaches, following
modern equipment have been recommended:-
Automated Wheel Diagnostic System
Mobile Lifting Platform
Bogie/Car body lifting System
Waste removal system for Bio-Toilets/Vacuum Toilets
Automatic in-motion Train Washing System
Bogie turn table.
Bio-Toilet evacuation machine
5.0 Other Facilities
Other facilities such as boundary wall, pliable road throughout the coaching
depot, concrete flooring, service rooms, proper lighting and their accessories
have also been proposed.
6.0 Coaching Depot Layout

18.1 Technology:
A. Wheel diameter/wheel profile measurement (laser based)
The moment wheel passes over the rail, a beam of light is passed on to
the wheel from under it. The emerging rays are received by a receiver
and fed to a computer which evaluates the inputs. By using Opto-
electrical equipments and high resolution digital cameras and
computers which are capable of accurately processing the digital
data, the wheel profile measurement can be performed.
BB.. DDeetteeccttiioonn ooff ffllaatt aarreeaass && oouutt ooff rroouunndd
Along a stretch of track equal to the circumference of the wheel, distance
between the track and the wheel crown is continuously measured
electronically and evaluated by a computer. The flat areas are detected by
the variations of height between track and the wheel crown. The difference
between largest and smallest diameter will give the measurement of
out of round.
CC.. CCrraacckk ddeetteeccttiioonn
Two ultrasonic scanning heads each are integrated in the left and right rail
of the track, when a wheel passes through the scanning heads, this transmits
ultrasonic impulse for the detection of the cracks on the tread surfaces.
By providing wheel diagnostic system, it will pre-warn the condition of
wheels. This will help in -
Average planning of wheel profiling and wheel change.
Improved safety and reliability
Improved wheel life.
Reduction in examination time and manpower.
Based on above benefits the provision of wheel diagnostic system is justified.

23.1 Photograph of Automatic in motion train washing system
Cleaning of coaches is the problem of the entire Indian Railways. Washing
and cleaning of coaches is one of the though and critical jobs to be carried
during train examination. The train movement on the such dusty/sultry
climate of the region, to ensure desired level of cleanliness of coaches of
Railways passenger trains is a real challenge. The rakes of these trains are
examined and maintained at C&W Depot During examination of these
rakes, internal and external cleaning and washing of coaches is being
carried out. It is observed and studied that oily & sticky smoke emitted by
Diesel Locos especially in tunnels result in sticky soot and stains being
formed on the coaches thus resulting in a real problem of cleanliness of the
coaches and this has attracted public criticism also. As the staff is limited,
CAMTECH/2014/M/MFCD/1.0 41
Hand Book on maintenance facilities in coaching depot on IR November - 2014
the desired level of cleanliness cannot be done satisfactorily by
conventional method within limited time period.
23.2 AUTOMATIC COACH WASHING PLANT
To overcome the above problem of coach cleanliness, a method of external
cleaning of coaches by high-pressure water jet pump was adopted earlier.
Seeing at number of staff involvement in carrying out coach cleaning, coach
washing plant is developed by CAMTECH. In this plant, external cleaning
of coaches of a rake was done at NGP, Madgaon & Kurla by horizontal
rotating nylon brushes while passing through.
Eight powered nylon brushes were provided in this plant for the purpose of
rubbing of soap solution and cleaning of dirt on external surface of coach .
1.Stages of
a) Pre-wash,
b) Spraying of pressurized soap solution mixed with compressed air.
c) After wash with high-pressure water jet were developed and
incorporated in this washing plant.
In addition to horizontal nylon brushes, two Coir brush fixtures were
developed and fitted in this plant. These coir brushes were static (non-
rotating type) and fixed in one position for the purpose of even application
and rubbing of soap solution on surface of coach, thereby sticky particles of
soot and dirt get loosened and removed. But this coir brush could not touch
and clean the area near window-sills, upper and lower portions of coach
since upper portion of coir brush was obstructed by coach indication lamp,
indication board, destination board and lower curved portion (turn under) of
coach due to less stiffness of coir brush. Hence these portions were used
to be cleaned manually by available staff.
This plant is developed with keeping in view the following points in mind.
a) Less and economical maintenance of the modified washing plant.
b) Less manpower requirement for operation and maintenance this plant.
c) 95% exterior cleaning of a entire rake of 24 coaches is to be achieved
within 35-40 minutes.
d) Reduction in water and soap solution consumption compared to the
conventional Manual coach cleaning.
e) Reduction in power consumption by using automation.
f) Cleaning and disinfection of underneath portion of toilet by High
pressure jets.
g) Bogie side cleaning by high pressure jets.
h) Roof cleaning of Coach by horizontal nylon brush.

Hand Book on maintenance facilities in coaching depot on IR November - 2014
Water is supplied from overhead tank of 40000 ltrs. capacity to underground tank
of 10000 liters capacity (shown in figure). Water from under ground tank is
supplied to coach washing plant for Pre wash and After wash stages, by 3 HP
pump along with stand by, are located inside pump house. Soap solution is made
in overhead plastic tank of 1000 ltrs. and this soap solution is supplied to coach
washing plant for Spraying of solution stage, by one HP pump. Water pipe
connections for Pre wash , After wash , Toilet and Bogie cleaning stages are made
from 1" and 2" pipes and soap solution pipe connection is from 1" pipe. Electrical
switchgears and control panel are provided for 3 Pumps (1 for soap solution and 2
for water),motors (each 3 hp)of 1 horizontal nylon roof cleaning brush and 6
vertical cotton brushes and 2 vertical nylon brushes for soap solution rubbing, in
the pump house which is located near to washing plant. Compressed air supply,
which is already available at pit line, is tapped for soap solution spray.
Both structures and vertical brush unit have been painted with two coats of epoxy
primer and paint. Since this Iron structure and sub assemblies are more prone to
corrosion due to existing salty weather and acidic/alkaline soap solution used in
washing plant, epoxy painting is one of the better options to reduce corrosion and
the cost.

25.0 PROCESS OF COACH CLEANING AND WASHING IN DIFFERENT
STAGES
25.1. PRE-WASH: A rake is moving at speed of 5 KMPH during cleaning
and washing of coaches through this plant. In this stage a diffuser type
sensor is provided for sensing coaches of a rake. As soon as this sensor
senses first coach of a rake, water starts spraying on external surface of
coach through number of holes provided on water pipelines erected around
in a row.
25.2. SPRAYING OF SOAP SOLUTION: In this stage, diluted soap
solution is sprayed on coach surfaces including two sides and roof through
seven sprinklers. Provision is made for mixing of compressed air with
pressurized soap solution inside the sprinklers to get more bubbles formed
when it strikes with coach surface.
Two sides and roof of
coaches are completely
wetted by low velocity
sprinklers at this stage,
some loose dust & dirt is
washed away from coach
surface and
simultaneously, coach
surface is made uniformly
wet, which help in even
application of soap
solution on coach body.
Due to release of surface tension in
bubbles, dirt particles are loosened
and washed away easily. Flow and
quantity of soap solution can be
controlled and adjusted by operating
spindle nut on sprinkler and both
valves provided on soap solution
line and pneumatic line.
CAMTECH/2014/M/MFCD/1.0 46
Hand Book on maintenance facilities in coaching depot on IR November - 2014
25.4. SOAKING OF SOAP SOLUTION:
In this stage, soap solution is allowed to soak completely for approx.1
minute in normal washing process. This stage is automatically achieved
while rake is moving at 5 Km/h. through coach washing plant, since stage 3
and stage 5 is kept apart at 30 meter distance. During this stage, soap
solution, is chemically reacted with dirt.
25.5. MOISTENING OF SOAP SOLUTION:
In this stage, moistening of partially dried soap solution is carried out by
sprinkling of very low-pressure water through number of nozzles provided
on a water pipe line. Hence soap solution applied on roof and sides of
coach become wet before rubbing by horizontal and vertical brushes.
25.3. RUBBING OF SOAP
SOLUTION:
This stage is especially incorporated to
get more effective cleaning. In this
stage, soap solution is rubbed and
made even application on both sides of
coach by two vertical nylon brushes
one at each side of coach .This stage
comes into action as soon as sensor at
second stage is activated.

25.8.MOPPING OF WATER: After wash, coach body become
completely wet hence it require mopping. Two vertical brushes with
soft cotton threads are provided each on either side. These brushes
start mopping of water particles on sides of coaches as soon as coaches
pass through these brushes.
This stage is specially effective for
cleaning of AC glass windows where
small water drops are always sticking
and staining glass giving discomfort to
passengers when they are looking
outside through such windows. These
brushes are also used for buffing of
coaches to get shining by rotating it in
dried condition when rake is moved
from pit-line after examination. Since,
requirement of soap solution is less for
external cleaning of rake by this washing
plant. Cost incurred in normal external
cleaning of a rake of 21 coaches is Rs.
400 approximately. This cost includes
cost of material like soap solution and
cotton ropes (which are normally
replaced once in a month) and cost of
electrical power.
25.7. AFTER WASH: In this
stage, washing of roof and sides
of coaches are carried out after
rubbing of soap solution by
vertical and horizontal brushes.
High-pressure water is sprayed on
coach surface through eight high-
pressure sprinklers to wash coach
completely. In this stage, washing
of roof takes place just before
washing of sides by spraying of
water through high velocity
sprinklers provided at top of
structure. This arrangement is
made purposely to allow dirty
water after roof washing to flow
down on both sides of coaches
before washing of sides of
coaches.

27. 0 Justification of ACWP proposed for Coaching Depot
Automatic Coach Wash Plant : Cost Rs. 4.0 Crores Assuming no. of rakes examined per day in a depot = 6 rakes Average no. of coaches per rake = 21 Total no. of coaches examined per day = 126 Man power required for outside cleaning = 0.6 man/coach Saving in manpower for 108 coaches ( per day) = 126*0.6 = 76 men days Considering average wages of Rs.12000/- month or Rs.400/- day Monetary savings per year = 76x365x400 = 1.11 Crore The ROR is expected to be about 15 % Intangible benefits 1. Saving of water with ACWP (with 60% recycling) =6000 litres/rake Saving of water per day for 6 rakes = 6000x6 = 36000 litres = 36 kl Water is a scarce commodity in several areas and conservation of water is imperative
to save this invaluable natural resource.
2. Since the work of external train washing will no longer be carried out at pit line,
drainage problems will be less and the working conditions will improve, leading to better
productivity.
CAMTECH/2014/M/MFCD/1.0 51
Hand Book on maintenance facilities in coaching depot on IR November - 2014
28. Justification of Coach Lifting Plant proposed for Coaching Depot Cost : Rs.3.0/- Crores
Justification: At present ineffective % of coaching stock in sickline is 2.5 to 3 %. Underfloor
carbody lifting plant is proposed for lifting of coach body for maintenance in the sick line for
reduction in lifting time and safety in operation. By providing UCLP the lifting time of coaches
will be reduced considerably. On an average 4 – 6 coaches are lifted in a major coach depot.
Assuming 2 hrs. saving in lifting and lowering of coach the average saving is about 2 x 5 coach
hrs.
Annual Saving = 2 x 5 x 360 = 150 coaches in a year
----------------
24
Annual saving in Rs. =150 x 30000 = 45 lacs per annum
Further there will be saving of manpower and also ensure safety at work.
29.0 Covered shed
Well lighted all weather covered shed for examination and maintenance of subassemblies as per
Railway Board‟s letter no.97/M(C)/137/1 Vol.VI dt.09.06.04. The proposed pre engineered
building covered shed is cheaper than conventional one (Conventional shed Rs.25 Cr. v/s PEB
shed Rs.20 Cr.) The pre-engineered buildings covered sheds have following features:-
Simple design and light foundations
Standard component connections
Fast and standardized erection process
Low weight flexible frames offer higher resistance to seismic forces
Future expansion is simple and cost effective
Lighter structure weight
Aluminum sheet offers high corrosion resistance
CAMTECH/2014/M/MFCD/1.0 52
Hand Book on maintenance facilities in coaching depot on IR November - 2014
30.0 Justification for all weather shed for Coaching Depots
Covered all weather shed has been proposed for coaching depots. Detailed justification is as
follows –
1. Earlier the examination was carried out every 1500 Kms. Now with the latest
instructions for coaching train examination, round trip examination is carried out every
3500 Kms. Any laxity in examination is detrimental to the quality, reliability & safety in
operation.
2. Examination has to be carried out in limited time schedule of 6 hours, which involves
external washing, internal cleaning, under gear examination, brake gear checking, wheel
defects examination, change of springs, brake blocks and other defective fittings.
Examination in the open sky is particularly arduous in rainy season and in extreme hot
and cold weather conditions.
3. In case of working in adverse weather like heavy rains, not only the productivity of staff
is affected, it also leads to detaining of rake for longer period of 8 to 10 hours (as
compared to 6 hours scheduled time given for attention).
Financial Justification –
No. of rakes attended per day : 6 nos.
(at 2 pit lines)
No. of coaches attended per day : 126 nos.
(av. 21 coaches per rake)
Loss of time while working in Extreme
weather condition (@ 3 hours per rake) : 126 x 2 = 252 hours per day
No. of days with extreme weather condition : 180 days.
In a year
Total loss of coach hours : 252 x 180 = 45360 hours.
Total loss in coach days :45360/24= 1890 coach days.
Loss in term of earning potential of coaches : 1890 x Rs. 30,000
= Rs.5.67 Crores.
Cost of covered shed : Rs. 20 Crores
Break – even point : Less than 4 years.
The ROR is expected to be about 15 %
CAMTECH/2014/M/MFCD/1.0 53
Hand Book on maintenance facilities in coaching depot on IR November - 2014
Apart from above, there is loss of punctuality due to delayed availability of the rake, which
affects the operation of other trains also. The loss due to poor reliability leading to enroute
breakdowns can be minimized by the use of covered sheds. With the improvement in working
conditions, the quality of safety checks and overall safety shall be improved. Better working
conditions are bound to improve staff morale and are likely to reduce absenteeism due to
sickness resulting from working in adverse weather conditions. Therefore, covered shed is
desirable from techno – commercial considerations.
Better outturn with proposed facilities
With one hour saving in examination time in pitline due to attention of rakes in better working
condition
Savings expected in time required for attention = 1.5 hour
( due to better working condition)
Saving of coach hours (for 108 coaches examined / day) = 178 coach hrs.
As per traffic account figures the earnings per coach per day = Rs.30000/-
Monetary savings (in terms of earning capacity) = 178/24 x 30000 x 365
= 8.1 Crores
This is in addition to manpower savings due to introduction of various M&Ps like Automatic
Train Wash Plant and Wheel Diagnostic System.
Overall Justification: Cost of project : 60.55 Crores Savings due to saving in examination time on pit line = 8.1 Crores
Savings due to covered shed = 5.67 Crores
Savings with ACWP = 1.1 Crores
Savings due to Coach lifting system = 0.45 Crores
Total savings = 15.32 Crores per year
Break – even point : Less than 4 years.
The ROR is expected to be about 15 %

31.0 PROPOSED LIGHTING SOLUTION OF COACHING DEPOT
1.0 RECOMMENDATIONS
The illumination level for all working areas i.e. above catwalk, below catwalk
and underpit should be 100-150 lux for smooth and efficient working.
For overhead lighting under covered shed for the purpose of general shed area
and above catwalk lighting, metal halide lamp fittings blended with energy efficient T5
fluorescent lamp fittings with Inverter backup are recommended.
Metal halide lamps are recommended in place of mercury/ sodium vapour lamps
due to its best colour rendering properties. Metal halide excels in meeting the complex
demand of energy efficiency, light quality, light output and lamp life.
The basic problem with metal halide lamp is its high re-striking time (approx. 4
to 6 minutes), to avoid the total blackout during the above re-striking period after
restoring the power supply, the over head lighting is blended with energy efficient T-5
fluorescent lamps at each alternate position.
Multiple T-5 fluorescent lamps with electronic ballast have following beneficial
features:
Energy efficient (lumens/ watt is 90 to 100)
Instant start- no flickering & continuous illumination.
High colour rendering index i.e. true colours
Uniform distribution of illumination i.e. no shadow area at work place.
High power factor i.e. more than 0.95.
For illumination below catwalk and under-pit, Power LED based luminaires are
recommended. LED based energy saving lighting have following beneficial features:
More power to light instead of power to heat.
Energy efficient (Lumens per watt 90 to 110 lumens).
Pure white light, high colour rendering index i.e. true colours.
Long life span, more than 10 years. Eliminates maintenance cost on bulb
or CFL replacements.
For directed maintenance, staff may use helmet based LED lights for precision work.

33.0 Suggestions given by Zonal Railways for Pre-Fab pit line &
coaching depot infrastructure during seminar on 21.07.2014
Pit line: Dy CME/NWR, Sr DME/BSP & Dy CME/GKP stated that prefab pit line in line with
DMRC will be suitable but both side catwalks are required alongwith long span supports below
catwalk.
Catwalk: Catwalk is necessary for changing of destination boards, cleaning of exterior,
attention to doors, cleaning of roof and attention to ventilators. But these catwalks make clumsy
situation due to supporting pillars, hence it is suggested that pre-fab longer span catwalks may
be developed for better and safe maintenance.
Pre-Cast tiles: For free movement of staff from one pit line to other pit line at entry point, floor
of pre-cast tiles for atleast half of the coach length should be done for safe travelling.
Lighting arrangement: Light fittings of sufficient lux should be installed on Catwalk pillars for
under gear and trolley inspections. Single phase Welding sockets, and spare plug for hand lamps
should also be provided on this switch board.
Surface wheel lathe machine: Surface wheel lathe machine is required for coaching depots
having holding more than 250 coaches.
Maintenance bay shed: Lay out and estimation for covered shed should be done in line with
ROH depot ADI and TKD. The details may be collected from them.
Hydraulic Jacks: Hydraulics Howrah JET. And Ferro mysore are the sources for lifting
platforms.
Cleaning Machines: Sources for cleaning machines are , Karchar, Roots India, Johnson Divery
etc. Specifications may be collected from them
Revision in codal life of Linen: Some of the Railways have given suggestions that codal life of
bed sheets and blankets to be reviewed for better management of linen items.
