Description of the Bug

Been playing more with trains in my world and I think either the monorail engine's weight should increase or the traction multiplier should be higher. With 2 full freight cars and a config of 10kg per item, a 12000kg engine is attempting to pull (20,000 + 64,000) * 2 = 168,000kg. The wheel slip is nuts and even a 1% grade slope is too much for it. Changing tractionMultiplier to 4.0 in immersiverailroading.cfg makes it bearable to use, but if we're enabling more types of trains in the future maybe it's better to adjust the engine weight.

Also sometimes encountering weird things like massive amounts of drag preventing the engine from accelerating faster than 1 km/h per 10-20 seconds, followed by the freight cars self-disconnecting. If I keep moving I don't really see this, also I last saw this before I changed my traction from 1.0 to 4.0. This is an IR bug I saw mentioned so I doubt much can be done here.

Reproduction

1. Create a monorail engine pulling 2 full freight cars.
2. Try to go up a gentle slope of 1% grade or less.
3. Roll backwards.
