Every time a Bharat Heavy Electricals Limited (BHEL) rake leaves the car shed to ply on the central line during peak hours, Central Railway (CR) officials keep their fingers crossed hoping that the particular train completes its journey without disrupting the day’s schedule. On any given day, seven to eight such rakes ply on Central main, Harbour and Trans-Harbour lines.

The 14 rakes, assembled by the BHEL, were introduced on the Central line in the year 2000. File pic for representation
