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.

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
