Jun8-15: The first ever retrofitted DC to AC Converted 12Car EMU 4501-4504 from Sanpada, which was outturned in July 2013, meant to ply for Mainline, and subsequently plied in Pune, finally got to ply on the mainline section of CSTM - Thane. This was the first EMU to test and taste AC Traction and first test service to depart CSTM which went to Kalva Carshed. While this EMU proudly entered Thane , the 3 Siemens ACDC EMU at siding, look as if they have been sidelined :) (Vijay Aravamudhan)
