The trial run for Metro 2A and 7 lines was flagged off on Monday, seven years after Mumbai saw its first such mass transit system chugging between Versova and Andheri. The new routes, also called Yellow and Red lines, will become partially operational in October.

Chief Minister Uddhav Thackeray launched the trial runs on 2A, connecting Dahisar and DN Nagar, and line 7 that links Andheri and Dahisar. For the next few months, the test runs will be done between Dahanukarwadi and Aarey stations.
