Bengaluru: Here’s how Namma Metro trains remain squeaky clean

BENGALURU: The first Metro train, which began operating in Bengaluru in 2011, is hard to distinguish from the most recently obtained coaches. With the only observable difference between the 2011 train and others is the serial number marking the procurement details, most Metro users might agree that its 50 trains and 64 stations are spick and span.

Across its 70-km network, the machinery and plant department of the Bangalore Metropolitan Rail Corporation Limited completes automatic washing and internal (heavy) cleaning of all trains over a two-week cycle, apart from the daily routine cleaning. TOI visited Metro’s Byappanahalli depot to witness the department’s three distinct cleaning processes.
