The Delhi Metro Rail Corporation (DMRC) has built Asia’s highest Automatic Train Washing plant in Sultanpur Depot on the under construction Central Secretariat-Gurgaon Metro corridor.
Since there was limited depot area available, the washing plant had to be built in a unique manner to suit the requirements of other facilities too. The washing plant has been strategically built on a ramp at a height of 6.7 metres above ground level.
DMRC officials said no other Metro system in Asia has a similar plant at such a height.
Built at a cost of Rs 45 crore, it will serve as a maintenance depot for the Central Secretariat-Gurgaon Metro corridor. The construction of the depot began in July 2008 and the depot is now almost ready.
Situated near the Sultanpur Metro Station, this washing plant is designed to carry out automatic washing of the external body of the Metro trains. It washes the side walls of cars in motion with the help of vertical brushes.
It takes about 4 to 5 minutes for complete washing of eight (08) cars of a Metro train.
The depot has 14 stabling lines that can accommodate 28 trains at a time. Apart from this, other facilities provided in the depot include a test track, two train inspection bay lines, two shunting necks, a filtration plant with pump-house and bore well, an electric sub-station to meet its power requirements.
