It is understood (from informal discussions with staff) that Pune and/or Miraj based Loco Pilots do not prefer EMD locos on Pune-Miraj Section (given a choice). They still like their good old WDG3A or WDM3A (single / twin unit) Engines. Hence, as of now, trains like Goa Exp, Maharashtra Exp, NZM-KOP Exp, ADI-KOP Exp are not getting WDP4D Engines. Sometimes PUNE WDG4 are seen with Goa Exp. Only SWR Trains (like KSK, CDG-YPR Exp, Bangalore-Jodhpur Group of Trains) which come with KJM WDP4 / UBL WDP4 EMD Locos to Miraj, continue with same locos all the way to Pune (and even for onward journey)!
