Due to line congestion problems, unavailability of platforms, line / points getting blocked by E or D locos as well as shunting engines, PUNE Operations has strictly said NO to anymore D to E or E to D Loco Changes at Pune (other than the existing / present day loco changes at Pune). Hence, Diesel Locos haul all the trains coming from LTT to Pune and many other trains coming from CSTM to Pune!
