Lets say a freight train has a bulk of 2000**, order to reach the target speed we'd need a total push of 20 thousand. So, 200 engines are needed, and they require a total of 1200 puissance per round. Since I'm assuming a magisterial principal, lets assume level 9 is the highest level involved. At that level it is easy enough to make UMD checks in the thirties, so I'll assume that each transformer can handle 35 ebbs/round. This means that 32 copper/wood transformer pairs will be needed to supply power to the engines.
Sorry to rain on your parade, but your train is impossible.

An Orthogonal Engine generates 100 push for 54 bulk. This gives a naked engine a velocity of a little over 55 ft per round (~6.25 mph).

Additional push requires a bigger engine and this scales linearly, so there is no way to break the 6.25 mph limit.
