Mumbai and India's first Air-Conditioned EMU local train finally got the green flag on Tuesday but with strict riders. If all goes well with the preparations, Western Railway intends to run the completely walkthrough vestibule train by December 25 or January 1, 2018 between Churchgate and Borivli to start with. While giving the final nod to the AC local, the Railway board has asked WR to comply with several safety norms for passenger safety, including educating commuters on opening closed doors, placing two fire extinguishers per coach, and providing steps as wide as the doors, as the train does not have a central rod due to automatic door closing facility.
