From the Steam forums (Assumption – not a tested theory iirc. Also keep in mind that wagons have a hard speed limit that the train won’t exceed)

 

Robbedem – some basic (simplified) formulas:

m = mass (ton)

a = acceleration (m/s²)

v = speed (m/s)

T = tractive effort (kN)

P = power (kW)

s = slope (°)

 

a = MIN [ T/m – g sin s ; 2 ( P/m – g v sin s)² / ( v (2P/m – g v sins s)) ]

vmax = P / m g sin s (provided that T/m > g sin s)

 

I don’t know the maximum slope in the game, but I guess it’s around 3,5°
