ROLLING STOCK
Present rolling stock and speed Passenger Trains at 90 - 160 KMPH Freight Trains at 60- 100 KMPH
Proposed rolling stock and speed Passenger Trains at 160 KMPH Freight Trains at 100 KMPH

TRACK FEATURESTRACK FEATURES
CurvesCurves Flattening of curves to accommodate
speed up to 90 KMPH without restriction Induction of HH rails on the curves.
P & CP & C 1 in 16 or flatter T/Os Use of thick web switches CMS crossings

TRACK FEATURES TRACK FEATURES Contd..Contd..
BridgesBridges- To be strengthen to take care of higher moving loads, high coefficient of augment, increased tractive and breaking forces and
others.
Level CrossingsLevel Crossings Manning of Unmanned LCs Interlocking of Manned LCs Provision of retro reflective boards for
improvement in visibility

INPUTS FOR MAINTAINING HIGH INPUTS FOR MAINTAINING HIGH SPEED CORRIDORS SPEED CORRIDORS
Frequent Training to P. Way Staff More safety seminars More refresher courses
Revision in USFD testing schedule Intensified high quality inspections Modification in temping cycle Strict check on flat tyre wheels Introduction of automation of
operation to minimise human error

ADVANTAGEADVANTAGE
Increase in throughput Improvement in turnaround
capacity of wagons More number of trains with no
significant investment Improvement in earnings
![Page 14: HIGH SPEED RAIL TRANSPORT G. P. Kosta CBE/S. W. Rly./Hubli.](https://reader036.fdocuments.us/reader036/viewer/2022082610/56649ddb5503460f94ad24a4/html5/thumbnails/14.jpg)
RECOMMENDATIONSRECOMMENDATIONS
Realignment of curves to suit higher speed and if necessary realignment of completed gauge converted tracks having series of sharp curves
Formation treatment to unstable formations
Provision of fencing at all trespassing locations to ensure no trespassing across high speed corridor
Provision of ROB / RUB for smooth passage of road traffic
Use of SPURT Car for USFD testing of rails
![Page 15: HIGH SPEED RAIL TRANSPORT G. P. Kosta CBE/S. W. Rly./Hubli.](https://reader036.fdocuments.us/reader036/viewer/2022082610/56649ddb5503460f94ad24a4/html5/thumbnails/15.jpg)
RECOMMENDATIONS RECOMMENDATIONS Contd.Contd.
Use of mobile flush but welding plant to minimise thermit weld failures and immediate attention
Use of corridor block for track works Use of 130 m rail panels
