The Hyderabad Metro Rail project is an international scale infrastructure project, featuring many technological attributes in its advanced communication support system. Hyderabad Metro Rail features state-of-the-art communication system for continuous communication between the central control, train operators and the station controllers. It features advanced signaling & train control technology, Communication Based Train Control (CBTC), which ensures better control of the trains.
In fact, Hyderabad Metro is the first elevated Metro rail project in India wherein the trains are controlled using CBTC technology. The trains will be monitored from the advanced Operation Control Centre (OCC) located in Uppal depot. The Operation Control Centre (OCC) is considered as the primary control centre, as well as back-up control centre for managing the operations during emergencies.
Axle Counter based fall-back system is a form of secondary train detection system, deployed across all the three corridors, which is a backup for CBTC. The signaling technology which has been deployed at the depots is based on the redundant Computer Based Interlocking (CBI) system.
Booster Transformers are installed across the three corridors at specified locations for minimizing interference with main communication lines. There are Receiving Substations (RSS) established at Uppal, Miyapur, Yusufguda, & MGBS that receive power supply.
Hyderabad Metro also consists of SCADA (Supervisory Control and Data Acquisition) system which offers highest level of support for the purpose of monitoring, controlling and command. A centralized Operation Control Centre (OCC) based in Uppal Depot controls the entire Power Supply and Traction System Equipment through SCADA.
Hyderabad Metro rail also incorporates the Automatic Train Operation (ATO) mode which monitors safe train operations. Some of the station equipments like Computer Based Interlocking (CBI), wayside ATP etc., constitute important signaling equipments for ensuring safe and uninterrupted train services.
