DMRC Invites Bids to Upgrade Delhi Metro’s RS-1 Rolling Stock

Delhi Metro Rail Corporation (DMRC) has invited bids to retrofit and upgrade 10 train-sets from its RS-1 rolling stock fleet which are operated across Delhi Metro’s 34.4 km Red Line (Line-1) and 65.35 km Blue Line (Line-3/4).

The 74 coaches in this overhaul contract were originally designed, built and supplied as 4 coach train-sets by the MRM Consortium comprising of Mitsubishi Corporation, Hyundai Rotem Company and Mitsubishi Electric Corporation in 2002. Over the years, BEML supplied intermediate coaches through 2 contracts (RS-6 & RS-13) to turn them into 6 and 8 coach train-sets.

Metro coaches typically have a lifespan of 35-40 years, so these train-sets having been in service for over 17 years are essentially facing a midlife crisis right now.
