NFR installs first-ever smart coach washing plant in Guwahati


Guwahati: Taking advantage of the technology and moving towards environmental sustainability, the North Eastern Frontier Railway (NFR) has installed its first Smart Automatic Coach Washing Plant (ACWP) at Kamakhya Coach Maintenance Depot here.


The plant, which has a multi-stage cleaning facility, was inaugurated on Wednesday by NFR General Manager Anshul Gupta.


“The system is eco-friendly and provides an efficient and affordable technique for cleaning the external body with maximum use of water. Currently, coaches are being cleaned manually, which takes time and water consumption. Is about to do so, “an official statement said.


The automatic coach washing plant ensures the principle of low recycling through its water treatment plant.


“It uses only 300 liters of water, of which 80% is recycled water and only 60 liters (which is 20%) of fresh water is compared to 1500 liters per coach in manual cleaning,” the statement said.

The plant can clean 300 to 350 coaches daily.


“The system is equipped with controlled chemicals and weak soap, which does not ensure pollution. It can save about 1440 liters of water per coach in cleaning activities, thus saving 34 thousand liters of water per rack of 24 coaches.


Coach cleaning through this process also saves manpower, thus reducing costs.


The plant is also equipped with an intelligent control system based on PLC (Program Logic Controller) which has an auto start system when the train enters the ACWP. It can count the number of coaches; calculate the speed of the train and make MIS (Management Information System) report.


It is also capable of self-diagnosis and automatically detects any malfunction in the system. As such, the state-of-the-art coaching system provides a better quality of cleaning than the traditional manual washing system.
