During the trials, the interface of the metro train will be checked to ensure there is no physical infringement with civil infrastructure during its movement on the track. The subsystems of the coaches will also be tested.

“Later on, in stages, the new signaling technology to be implemented on this corridor and the communication-based train control (CBTC) will undergo rigorous testing,” said a DMRC spokesperson.

The response of the train at different speeds, braking and the interconnection with the operations control centre (OCC) will be monitored. The behaviour of the track system and the overhead electrification (OHE), where snags are often reported, will be checked repeatedly.
