DMRC MD DR. MANGU SINGH REVIEWS OPERATIONAL ISSUES OF METRO, DIRECTS A HOST OF ADDITIONAL MEASURES
Delhi Metro Rail Corporation (DMRC) is going to take a host of additional
initiatives to further improve the services on all its corridors. The Managing
Director, Dr. Mangu Singh has reviewed the operational issues of the entire Metro
network closely and has directed the following measures, especially in light of
some recent failures.
Automatic Train Control
(ATC): On certain
occasions, the ATC onboard power cards have failed leading to disruptions. The
module failing the card has been identified and spare modules are being
procured. The module will be replaced on all cards as a preventive measure.
certain other sections, disruptions have also been noticed due to the failure
of onboard hardware (Train Interface Computer (TIC) Cards). The TIC Cards which
have high intermittent failures will be replaced within the next six months.
Automatic train control (ATC) is a train protection system
used in railways that involves a speed control mechanism in response to
Track Circuit: To
arrest the frequent cases of theft of copper made S Bond cables, steel made S
Bond cables have been installed at all theft prone areas of the network.
reliability Relay Boards are being provided in the Track Circuit system for
greater efficiency. The Relay Boards at NOIDA City Centre, Vaishali and Dwarka
Sector 21 have already been replaced while the same is going to be done at
Dwarka and Yamuna Bank.
Counters, which can detect the entry and exit of trains from a certain location
and can certify whether the section is clear for a second train or not, are
likely to be installed at all originating points on Blue Line, i.e, Dwarka,
Dwarka Sector 21, Yamuna Bank, NOIDA City Centre and Vaishali. This will be
helpful in minimizing disturbances.
Automatic Train Supervision
(ATS): Some disruptions have taken place due to
the failure of the Central ATS for the Blue Line, due to which train ids have
been lost and delays have occurred. To handle this issue, arrangement of a
backup Central ATS on standby mode is being planned.
Automatic Train Supervision (ATS) is
a system that provides the appropriate controls to direct the operation of
trains in order to maintain intended traffic patterns and minimize the effect
of train delays.
Measures already taken to
number of improvements have already been done in Rolling Stock and Traction (Over
Head Electrification) which have contributed in minimising disruptions. In
Rolling Stock, hardware and software related modifications have been completed
in 175 trains and maintenance audits have been done in 56 trains. An action
plan is being prepared based on the experiences of the past to prevent their
Traction (OHE) also, insulators have been replaced across the network to
prevent disruptions. Hands on training has been provided to staff at the
Northern Railway Electric Training Centre in Kanpur. An OHE Maintenance
Training Simulator has also been developed for providing enhanced training to
the Traction staff.
Delhi Metro continuously analyses all the operational aspects of its network
and brings in the necessary modifications to further improve and provide
uninterrupted passenger services. The Delhi Metro system by design is ‘fail-safe’
in nature. Therefore, whenever a failure takes place, the system slows down or
stops only to ensure the safety of the passengers on board thereby resulting in
delay of services.
