Speed is the distance that the [[train]] travels in a second. The game measures distance using in-game meters. One meter equals one tile. For example if the [[train]] speed is .250 m/s the [[train]] advances one tile in four seconds.

The following graph shows the speed in relation to distance without engine upgrades in legacy and current builds with varying player count:

The formula for speed is a polynomial y = ax^2 + bx + c, where y is speed, and x is distance. The following table shows coefficients that fit the curves in the graph above quite closely:
