Greetings, All !

In the Indian content made for MSTS, there are few WAP4 Electric Locomotives that are used by players in various
activities to haul 24 coaches of a passenger train (usual scene in Indian Railways). But, some locos are unable to
pull all 24 coaches. What factor I must change in the .eng file of such locomotives so that it can easily haul 24 coaches
in both, MSTS & Open Rails?!

Thanks in advance
