Western Railway (WR) on Tuesday faced a six-hour disruption due to a cable defect and related signalling issues, which led to the delay of 220 trains and the cancellation of 90, apart from chaos at stations. The four-month-old Red Line 7 and Yellow Line 2A, on the eastern and western sides of WR, ameliorated the situation, recording their highest-ever footfall in the process.

The Metro lines, which proved their mettle on Tuesday, have a 10-12-minute train frequency. However, transport experts said a deeper kind of integration with the existing railway network, which has never been thought of, could have easily boosted the crowd count and alleviated the situation at WR stations.
