The Railway Board on Saturday ordered a double-locking arrangement for all relay rooms with train controlling mechanisms, relay huts housing signalling and telecommunications equipment of level-crossings, and point and track circuit signals, officials said. The missive to the railway zones is the latest in a series of directions issued since the June 2 accident involving three trains in Odisha’s Balasore which killed more than 280 people.
The order indicates that the “access to the relay room” was key to the “signalling interference” that caused the Coromandel Express to take the loop line at Balasore and crash into a stationary goods train.
