Re: Milwaukee Road substation locations if the Gap had been electrified

The limitations on how far a substation can provide power is defined by how much current can be consumed and how much voltage drop is tolerable.

Voltage drop is simply current times resistance for DC wiring.

A simple rule of thumb is that the resistance of 1 foot of 1 cmil wire (i.e. a round wire with a diameter of 0.001", which is 1 mil) is 10.6 ohms, thus 1000' feet of 1000Mcm cable will have a resistance of 0.0106 ohms.

The resistance of rail is about the same as a copper conductor with an area of 10Mcm per pound per yard, a pair of 90 lb rails is equivalent to a 1,800Mcm copper cable.
