The IRFCA loco roster lists all the Baaz locos as WDP4 only. But, while the original WDP4B class was a modified version of the WDG4, later on many WDP4 locos, quite a few of them from KJM, were retro fitted with 6 traction motors, but the loco class was not changed.
please wait...Translate to HindiIRFCA loco roster me saare Baaz loco ko sirf WDP4 hi mana gaya hai. Par, original WDP4B class jo WDG4 ka modified version tha, bad mein kayi WDP4 locos, khaaskar se KJM se kuchh locos, ko 6 traction motors ke saath retrofit kiya gaya tha, par loco class nahi badla gaya.
