A metro spokesman said that during trial runs, the interaction of the trains with civil structure are checked to ensure that there is no physical blockage during its movement on the tracks.
"The entire signalling system also undergoes rigorous testing. In addition, train response at different speeds, braking and inter-connection with the Operations Control Centre (OCC) are monitored during the trials," the spokesman said.
Delhi Metro Railway Corporation (DMRC) had made its foray into Haryana five years ago and with this project the DMRC will further spread its operations in the neighbouring state.
After trial runs, DMRC will have to get the mandatory Commissioner for Metro Rail Safety (CMRS) clearance, after inspecting the line for all safety parameters for passengers.
