The washing plant in the Sultanpur Depot on the under-construction Central Secretariat-Gurgaon Metro corridor has been strategically built on a ramp at a height of 6.7 metres from the ground level.

“No other Metro system in Asia is known so far to have built such a plant on ramp at such a height,” Delhi Metro spokesperson Anuj Dayal said.

The plant is designed to carry out automatic washing of the Metro trains. The water used in the process is re-circulated in the system after cleaning the train. It would take about five minutes for washing of eight cars of a Metro train at the plant.

The depot has 14 stabling lines that can accommodate 28 four-coach trains at a time. Apart from this, the depot has a test track, two train inspection bay lines, two shunting necks, a filtration plant with pump-house and borewell, and an electric sub-station to meet its power requirements, among others.

“Constructed at a cost of Rs.45 crore (Rs.450 million), Sultanpur depot will serve as a maintenance depot for the Central Secretariat-Gurgaon Metro corridor. The construction work of the depot began in July 2008 and is now almost ready for providing its services,” Dayal said.
