NEW DELHI (Metro Rail News): The rather quiet south Delhi neighborhood of Jangpura is on its way to becoming the nerve center of the high-speed Regional Rapid Transit System (RRTS) connecting the capital with Meerut, Panipat, and Alwar.
While the hub of the system will be located in Sarai Kale Khan, where all the three corridors will originate, Jangpura is being chosen for operational reasons.
“Since our first services will start at 6 am, we need trains available near Sarai Kale Khan,” explained Sudhir Kumar Sharma, spokesperson of National Capital Region Transport Corporation (NCRTC), which is executing the project.
He said that creating a depot would have required a lot of costly lands and that is why NCRTC plans to create stabling lines at Jangpura, where there was government land available. Some trains could be stationed there at night for the first morning services, though the maintenance depots for the Delhi-Meerut corridor would be in Duhai and Modipuram.
NCRTC has chosen Jangpura not only for the stabling lines but also as the master OCC. “Our emergency response teams will be stationed at Jangpura and all emergency equipment will be located there,” said Sharma.
“We also needed a centralized control center from where all the lines could be seen at one point. Jangpura fitted this bill.” At present work is underway for the 82-km long Delhi-Ghaziabad-Meerut corridor.
A 17-km section between Duhai and Sahibabad will be the first to become operational in 2023. A preliminary OCC will be set up at the Duhai Depot area for monitoring train movements. However, by 2025, when the entire corridor is expected to become operational, a master OCC will have come up at Jangpura. It will not only control trains on the Delhi-Meerut corridor, but also on the Delhi-Panipat and Delhi-Alwar corridors to follow.
Since RRTS is a high-speed rail-based system, at any point in time, there will be a number of trains running on the track. Coordination of the train runnings, therefore, is crucial.
OCC will help keep track of train speed, movement and other related systems like the timetable, traction, train position, ATP (automatic train protection), ATO (automatic train operation), ATS (automatic train supervision) and auxiliary equipment like air-conditioning and ventilation systems.
The project will be the first in India adopt the ETCS (European Train Control System) Level 2 signaling system, which has among the most advanced train control features. “The system continuously calculates a safe maximum speed for each train,” an NCRTC official disclosed.
“The Level 2 system is radio-based and displays signaling and movement authorities in the train cab. The train sends data on its position constantly.”
The official added, “The OCC room will have a large electronic display showing critical information related to the movement of the trains. Since all the data come in real-time, every minute movement of the train is monitored at OCC. In case of lags, he said, the engineers would be able to first investigate from OCC itself.
