The lines at the station were electrified on 13 April 1979, with the electrification of the Chennai Central–Gummidipoondi section.
[1] Tondiarpet diesel loco shed is located to the north of the station.
Established in 1972 with the induction of a WDS4B-model diesel locomotive (WDS4B #19202), the shed was built to cater the shunting requirements of the marshalling yard at Tondiarpet, the goods sheds at Royapuram and Salt Cotaurs, and the coaching depot at Basin Bridge in Chennai division.
In 2001, these were replaced with the WDM7-model main-line locomotives for passenger and yard shunting work.
In April 2007, mainline WDM2-model locomotives were additionally inducted for hauling goods.
