1. HIGH SPEED RAIL TRANSPORT G. P. Kosta CBE/S. W. Rly./Hubli

3. BACKGROUND • World Scenario: Speed up to 500 Kmph, Dedicated track & Rolling Stocks. • Present Position – Indian Context MIXED TRAFFIC WITHSPEED VARIATION60-130 KMPH

4. Need for High Speed Transport Corridors • TO ADOPT LATEST TECHNOLOGY. • TO COPE UP HIGHER DEMAND for passenger and freight traffic. • TO COMPETE WITH OTHER SURFACE TRANSPORT SYSTEM.

5. Future Projections for INDIAN RAILWAYS • Increase in Passenger traffic by 30 to 40% in next 20 years. • Increase in goods traffic by 80 to 100%. • Nominal increase in track structure.

6. CHALLENGES BEFORE ENGINEERS • Present condition of Track • Formation treatment • Re-alignment of curves • Improving visibility at Level Crossings • Challenges to be faced in High Speed Transport Corridors - • For maintaining Track • For maintaining Bridges • Safety at LC gates

7. GOLDEN QUADRILATERAL • New Delhi – Howrah • New Delhi – Mumbai • New Delhi – Chennai • Mumbai – Howrah • Mumbai – Chennai • Howrah – Chennai

8. OTHER SPECIFIED ROUTS • Ballary – Hubli – Vasco-Da-Gama section on South Western Railways and other sections.

9. 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

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

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

12. INPUTS FOR MAINTAINING HIGH 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

13. ADVANTAGE • Increase in throughput • Improvement in turnaround capacity of wagons • More number of trains with no significant investment • Improvement in earnings

14. RECOMMENDATIONS • 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

15. RECOMMENDATIONS 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

16. CONCLUSION • Optimisation of existing Line Capacity • Improvement in turnaround of the wagon • Maximization of earnings with very less investment
