Sorry if this has been suggested before. But in the creator, it would be nice to be able to have the locos such as 37, 45, 47, 66 etc to be able to haul both passenger and freight, rather than just, for example, freight for the 37 and passenger for 45, and also be selected as a light engine (in the case of the 37). Obviously it would be silly to have things such as a HST loco (43?) having this. I’ve noticed the cabs of some have the ability to select between brake types for passenger and freight workings it would be good to be able to put this to use.
This is a great idea which will hopefully be implemented in the future. A lot more choice of consists is a must have feature. Lastly, the HST Class 43's could be run light engine, but in pairs back to back which has happened in the past.
I'm sure that's close to the top of the list of desired features players want. It would really make the game more enjoyable.
