BACKGROUND


World Scenario: Speed up to 500
Kmph, Dedicated track & Rolling
Stocks.
Present Position – Indian Context
MIXED TRAFFIC WITH SPEED VARIATION
60-130 KMPH
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.
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.
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

OTHER SPECIFIED ROUTS

Ballary – Hubli – Vasco-Da-Gama
section on
South Western Railways
and other sections.
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 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

TRACK FEATURES

Bridges


Contd..
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

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
ADVANTAGE




Increase in throughput
Improvement
in
turnaround
capacity of wagons
More number of trains with no
significant investment
Improvement in earnings
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
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
CONCLUSION



Optimisation of existing Line
Capacity
Improvement in turnaround of the
wagon
Maximization of earnings with very
less investment
