New Delhi: When Delhi Metro`s Phase-III
becomes operational by 2016, trains will run at very short
frequencies of 2 minutes thanks to an advanced signalling
system that would be put in place.
The advanced technology, the first-of-its-kind in the
country, would reduce the waiting time of the passengers as
train would run at increased frequencies.
Currently, trains on Delhi Metro`s existing six corridors
run at an average frequency of 2.5 minutes and this would be
reduced to 1.5 to 2 minutes when the Phase-III is completed by
The advanced technology -- Communication Based Train
Control (CBTC) system -- will be introduced enabling the Metro
to run trains at such short frequencies.
"In Phase 3, signalling technology capable of running
trains at a frequency of 100 to 120 seconds will be used to
facilitate the running of trains at very short frequencies on
the Metro network," a Delhi Metro spokesman said.
CBTC is a railway signalling system that makes use of the
telecommunications between the train and track equipment for
the traffic management and infrastructure control.
By means of the CBTC systems, the exact position of a
train is known more accurately than with the traditional
signalling systems, resulting in a more efficient and safe way
to manage the railway traffic.
"With this technology, more train trips will be possible
with the existing rolling stock," the spokesman said.
Delhi Metro currently has a network of over 185 km and
carries around 20 lakh people a day. The Phase-III envisages
connecting another 103 km of the national capital with Metro
through four corridors.
