WR successfully converted the slow lines on Virar – Borivali section from 1.5 KV DC to 25 KV AC on Sunday, 28th February, 2010. A mega block of 6 hours from 9.30 to 15.30 was undertaken to complete this work. The work was completed at 15.00 itself, 30 minutes before schedule. Due to the conversion, only MRVC rakes and the few converted AC/DC rakes will now ply beyond Borivali. I was present at the Dahisar neutral zone (spot where actual transition from AC to DC and vice versa takes place) on that day. Click here to see a few photographs of the conversion clicked by me.
