Read in today's dna. Chetan bakshi wants to impose a speed restriction of 15kmph between kurla and cstm to which central railway has refused and he wants most of the bridges dismantle due to their heights for a complete dc ac conversion along with other conditions between thane and cstm. It looks like it wont be possible for some more time i believe. Chetan bakshi says, "These are vital safety issues and the conversion can see the light of the day only after a solution is found”.
