Delhi Metro is a greenfield development of a 58km heavy metro system with 38 stations and 2 depots, for
which Bombardier Transportation are currently introducing a
CITYFLO 650 communications based train
control (CBTC) signalling and control system. The line is a mixture of above ground and tunnel areas,
leading to design consideration of system functionalities required to be able to handle operations in either
The vehicles on the line are designed to be operated in both UTO (Unattended Train Operation) and nonUTO modes, both above ground and tunnel. The CBTC system functionalities and integration with the
rolling stock have therefore been designed to be able to operate with or without a driver across the different
line environments.
The introduction of UTO requires a CBTC system with a higher degree of automation, including fully
automatic depot storage and dispatch, automatic jog and creep at platforms and automatic handling of
emergencies between platforms including evacuation. It also requires increased remote visibility and control
through the provision of remote access to onboard CCTV at the OCC (Operational Control Centre) and
stations to provide the ability to remotely handle onboard issues for a train in UTO.
