BACKGROUNDBACKGROUND
World Scenario: Speed up to 500 Kmph, Dedicated track & Rolling Stocks.
Present Position – Indian ContextMIXED TRAFFIC WITH SPEED VARIATION 60-130 KMPH
Need for High Speed Transport Need for High Speed Transport CorridorsCorridors
TO ADOPT LATEST TECHNOLOGY.
TO COPE UP HIGHER DEMAND for passenger and freight traffic.
TO COMPETE WITH OTHER SURFACE TRANSPORT SYSTEM.
Future Projections for INDIAN RAILWAYSINDIAN RAILWAYS
Increase in Passenger traffic by Increase in Passenger traffic by 30 to 40% in next 20 years.30 to 40% in next 20 years.
Increase in goods traffic by 80 Increase in goods traffic by 80 to 100%.to 100%.
Nominal increase in track Nominal increase in track structure.structure.
CHALLENGES BEFORE ENGINEERS
Present condition of TrackPresent condition of Track Formation treatment Re-alignment of curves Improving visibility at Level Crossings
Challenges to be faced in High Challenges to be faced in High Speed Transport CorridorsSpeed Transport Corridors -
For maintaining Track For maintaining Bridges Safety at LC gates

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
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
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
CONCLUSIONCONCLUSION
Optimisation of existing Line Capacity
Improvement in turnaround of the wagon
Maximization of earnings with very less investment
