In the year 2013, had first posted that few rakes from MUTP-1 quota were still not manufactured (link to post). I had also sought information about them under RTI act. After that, one 9 coach rake was manufactured a couple of years ago. I am happy to inform that the production of these missing rakes has resumed. The first of these rakes was spotted at Chennai by a fellow railway enthusiast. It will reach Central Railway in the first week of new year.
Two more rakes are expected after this. They will definitely help CR to phase out old coaches. I am glad that the railways finally decided to manufacture these coaches.
