BACKGROUND

• World Scenario Speed up to 500 Kmph, Dedicated
  track Rolling Stocks.
• Present Position Indian Context
• MIXED TRAFFIC WITH SPEED VARIATION 60-130 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

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
