Please update the coach compostion of this train-- the slip coaches in the beginning attached at HW are SLR-S7-S6-B3-B2......Plus with recent electrification of GZB-SRE sector loco links have changed. The TKD WDM 3A does only DDN-HW, from where an e-loco along with slip coaches is attached, mostly BRC WAP4E/WAP5. PLZ UPDATE
