The branch line to the Coaling Plant was created with the purpose of transporting coal from the nearby mines to be distributed across the Island. For a time, Percy was put in charge of this branch line.
Being that the line is primarily for goods traffic, it only has one station, that being Miner's Halt. The line itself is known to have very steep gradients either side of the halt, which once aided Percy with stopping some runaway trucks. The branch line joins with The Main Line at a small junction just east of Suddery Junction.
