I used the excuse to check the shunt lead to get out some rolling stock and found it will take twelve modern wagons and two locos if needed. The engine servicing area will be to the right of the wagons.
The power for the tracks are soldered to the bottom of the rails.
The main line is the one with cement sleepers in the middle and the yard lead is the track on the left, the yard lead also crosses the main line to the engine service facility and other industries. None of the track is glued down yet to allow a bit of movement when laying the next section.
This photo is of a mock up of one of the industries serviced by the line leading from the engine terminal, I was thinking along the lines of a frac sand transfer facility and maybe some protestors.
