Bhai Dloco ki max speed WAG se better hai. Mostly WAG se delay cover karne ke waqt slow pad jati hai trains. I have travelled with DBRG CDG many times. With Dloco it could cover its an hour to 1.5 hour delay in GKP GD while with WAG it mostly is able to cover 45m to 1h delay. WAG's are good for freights but not for passenger trains.
