What can ICT do?
ICT is known to have made
immense impact in booking of railway tickets
can make an impact in
service management
tracking movement of goods
control of wagons
passenger amenities
can improve decision making and management
Not as well understood that ICT can
significantly enhance throughput on existing Railway Network enhancing Carrying Capacity
provide voice and data services for passengers
Carrying Capacity and Throughput
Total Carrying Capacity (people and goods) of Railways is inadequate considering large Indian population
capacity increase has not kept pace with economic growth
rail transport more energy efficient as compared to road transport
Train throughput can be enhanced
by adding tracks
expensive (Rs 2 Crores per Km), time consuming
by enhanced signaling (using ICT)
throughput enhancement by a factor of 5 possible on existing tracks
while retaining / enhancing safety
Throughput bottlenecks
Throughput is limited in run-through sections due to
only one train can occupy one block section at a time
slow down while approaching stations
signal operation time
efficiency in planning train movements and conveying commands
Train throughput is also severely affected by
slow down due to failure of track in one direction
bottlenecks at junctions and yards
Improving planning of train movements
Command and control of a train is centralised
Section Controller controls movement of all trains in section (150 Kms)
operations of all signals is decentralised at stations
uses voice communication on an omni-bus telephone line between Controller and Station Master used to convey control
12 telephone calls for moving a train from one station to another
results into reduced efficiency
Visual or intra-net link between Controller and Station Master can improve efficiencies
and enhance throughput by at least a factor of 1.5
