What kind of trouble can you get yourself into by changing the temperature outside yourself. At the moment the temperature can only be changed and remain fixed when you select a weather present. However what If you can make further changes and say have winter with light snow but minus 50 degrees ( i mean still keep it realistic obviously), but minus 50 would mean you'd see ice buildup and foggy cabins because the heaters will be running. Ice buildup on the locomotive and wagons would also be an interesting feature, chipping ice from the locomotive as an optional activity would add an to the realism aspect.
