Delhi Metro on Sunday commenced trial runs on the fully elevated 14 km-long Badarpur-Faridabad corridor, setting in motion the process of formally opening the line by June. The 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. “The first trial train on this section on Sunday travelled from the Badarpur to Old Faridabad Metro station,” said a DMRC official. A Metro spokesman said during trial runs, the interaction of the trains with civil structure would be checked to ensure that there is no physical blockage during its movement on the tracks. “The entire signalling system will also undergo rigorous testing,” he added.
