This is the first time Northern Railways is going for automatic washing system even though the Konkan Railways has adopted the technology much before it.
The high speed cleaning takes just 7 to 8 minutes to wash 24 coach rake compared to long time taken earlier. The plant has a capacity to work 24×7 with eight hour shift each. Officials said the new system takes only 240 litres per coach as compared to 1500 litres per coach through manual washing. Besides, Automatic Train Coach Washing System uses only 20 per cent of fresh water and while the balance 80 per cent is the recycled water.
