Concern over wear rate - limited maintenance window
Demanding alignment curving in 3 dimensions!
Special track-forms to reduce ground borne vibration
Need to minimise wheel and rail roughness
Dry conditions may give need for flange and top-of-rail friction management
Track-friendly trains
Cut the weight
Cut the unsprung mass
Design a suspension that curves well
Reduce yaw stiffness
But trade-off with stability – Crossrail a
challenge because a curvaceous central
tunnel is combined with straight and
relatively fast surface running
Controlling Friction
Too little Slip and slide
Too much Wear and misalignment
Flange lubrication Track or train?
Stick or spray?
Top of rail friction modification
Track or train?
Sanding Affects pointwork, track circuits, drains
Signalling
24 – 30 trains per hour target on
core route
Automatic Train Operation
necessary
ATO over ETCS (European
mainline cab signalling
standard) considered
Capacity of train-wayside
communication a risk
Proprietary ‘metro’ CBTC
system to be adopted for central
section
Integration with new and legacy
systems ‘on-Network’
Fitting Signalling Equipment on the train
Nominated sub-contract approach
Signalling contractor (Siemens) will sell CBTC items to train builder (balise reader, on-board computer etc.)
Rolling stock builder (Bombardier) will integrate with train and with on-board ETCS system
Rolling stock builder will test at his test facility
Transitions between different signalling systems to be proven
CBTC – ETCS
CBTC – legacy AWS/TPWS
ETCS – legacy AWS/TPWS
Traction Power
25kV at the catenary
50 kV auto transformer
system – reduces I2R
transmission loss
Strengthens supply for
existing users
Receptive for regenerative
braking
Solid bar conductor in
tunnel section

Tunnel Ventilation
Three objectives Fire incident management
Stranded train incident management
Long term maintenance of tunnel temperature
Separation of running tunnels and platforms
Rolling stock contribution Energy efficiency
Regenerative Braking
Fire load
Minimise pressure pulse
Telecomms.

WiFi?
Driver -only CCTV
Giving Driver best-possible view of platform
Risk of dragging persons along platform
Needs to work with Platform Edge Doors
Common system throughout Crossrail network
London Underground DOO CCTV practice
cameras on stations
screens in cab
Choice of wayside-train link
Platform Edge Doors / Information
Physical Clearance – ‘Gauging’
Limited by Tunnels, Bridges, Platforms etc.
KE determined by : Speed
Dynamic Behaviour of Suspension
Track Fixity
Curvature and Cant
Tolerances – track & train
Lower clearances necessitate extra track maintenance
Platform stepping distances must be maintained
PED entrapment to consider

Meets Sponsors’ Requirements

Class 345 Rolling Stock – Key Data
Overall requirements Driven by Sponsors’ Requirements in terms of capacity, passenger volumes and journey time – 1500 passengers per train
A train that works with new, recent (Heathrow branch) and legacy infrastructure
Standards Trains will be compliant with Conventional Loc.&Pass.TSI and NNTRs.
Train Size 163m (Initial GE services;) Expandable to 205m - Car length not prescribed
Gauge profile based on Class 319/MkIII coach- widespread UK gauge clearance
Train Formation Fixed formation- semi permanent couplers between cars .
Mechanical couplers at ends- for rescue and recovery.
Supply Voltage 25Kv Overhead - ‘Passive Provision’ for later fitment of DC (‘Dual Voltage’) equipment
Power and Performance 1ms-2 initial acceleration
90mph (145km/hr)
9%g full service brake rate (12% emergency brake rate). Typical ATO brake rate 7.5%g
Regenerative brake
Sectional run times to be achieved with a 10% contingency
42
Class 345 – Challenges
Reliability (Reliability, Reliability!)
Performance Dwell time management as important as inter-station times
Systems Integration
Interfacing with legacy infrastructure
Gauging, platforms
Signalling, EMC
Boarding and Alighting
Major topic of concern to railway safety bodies Tripping, falling between train and platform
Trapping passengers in doors- dragging along platform
Key concern of PRM legislation
Significant range of platform heights and gaps at legacy on-Network stations
Ease of boarding affects station dwell times and hence timetabling and energy usage
Size and number of doors, and internal car layout and station platform layouts all affect dwell time
Trade-off between gauge clearance and reduced stepping distances
44
Class 345 Rolling Stock – ‘Green’ Issues
Energy Consumption- Carbon Footprint Weight targets
Optimised regenerative braking
Timetabling and ATO settings
Driver Advisory Systems for ‘eco-driving’ in manual mode
‘Hotel load’ management features
Use of Materials - Responsible Procurement
Noise Noise TSI compliant
Interior targets based on recent UK practice
Targets for tunnel running based on experience
Undertakings in Crossrail Act re ground-borne noise and vibration
Drivers of energy consumption
Accelerating up to speed
KE = ½ Mv2
Weight effect
Aerodynamic drag
Also largely a (v2) issue
Traction chain efficiency (80-85%)
So regenerative braking does not give perpetual motion!
Auxiliary consumption
Transmission losses
46
Class 345 Rolling Stock – Fire Safety
SRT (Safety in Rail Tunnels) TSI category A the base requirement, as stations less than 5km apart
Running capability 5 minutes including traction
Mitigation of concerns around Open Wide Gangways
Material standards to match London Underground ‘deep tube’ practice
Research on fire size, smoke spread and ignition sources
Supplier to demonstrate ‘tenability’ assuming fire detection systems and active smoke management
47
Interior vision
Vision Realised
Exterior vision takes shape
Trains being built
Crossrail is at the point of transition from a
civil engineering project to a railway system
Customers will expect a seamless service
across a range of railway infrastructure and
operators
The train will be the common ‘touch point’
everywhere from Reading to Shenfield and
Abbey Wood to Heathrow
Some concluding thoughts
