24th October,2010. Badlapur (incl) - Kalyan (extl) [SE line] switches from 1.5kv DC to 25kv AC power. Its an historic event for Indian Railways altogether! 2217-2218 is the 1st electric mrvc emu to travel in AC after the conversion. One can find moterman's cabin attended by CR officials for safety measure. Eagerly waiting for mainline [Kyn-Cstm] to go AC.
