When will we get the Train Service?

It's been almost 4 years since the train service between Villupuram and Mayiladuthurai had been stopped due to guage conversion and the pity is that even after the completion of railways tracks, lining and other essential stuffs, the line line is yet to be opened for Passenger's service. The railways authorities site that there are few more works such as Construction of platform, Signals, setting up of level crossings are some of the work that is still on hold. But its definitely a lethargic move from the authorities.
