Major signalling upgrade work at Dahanu on Western Railway (WR) will lead to the cancellation and rescheduling of scores of suburban and outstation services this weekend.

“Due to non-interlocking work at Dahanu Road Yard on Saturday from 1 pm and Sunday from 8 am to 4 pm for replacement of signalling gears to change into electronic interlocking, several WR trains will be short-terminated, partially cancelled, cancelled, regulated or rescheduled,” Sumit Thakur, chief public relations officer, WR, said.
