Hyronymus.
That formula allows to calculate tractive effort. And the 'u' (mi) changes from 0,15 for some steam locos to 0,4 for modern equipment.
30% grade is way too much for rv. 20% s really steep.

Meeting Decisions:
* Nothing were really decided, but there where quite some discussion about it.
* Main voices:
- Have a clear maximum, to make the game clear to the players.
- Don't have a maximum, it will trade off to much.
- Use RRT style charts, that displays: max speed at various loads and slopes.
Status: Inconclusive. Open to discussion.

Clearly we have the means to calculate whether a train can actually start unaided (i.e. without the benefit of a push off, or a downhill start). Ultimately, a given amount of energy is required to start a vehicle or train of given mass, and the propulsion available either can or cannot bring it to the point of motion - there is no in-between. If you manage to beat the weight but not overcome friction, you haven't reached the point of motion.
Locked until the DD discussion arrives at this issue.
