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.
