Reminds me of the Black Mesa and Lake Powell Railroad (https://en.wikipedia.org/wiki/Black_Mesa_and_Lake_Powell_Railroad https://en.wikipedia.org/wiki/Black_Mesa_and_Lake_Powell_Rai...), which was a 117 km (73 mi) railway completely isolated from the rest of the US network, built with the sole purpose of shuttling coal from a coal mine to a power station. As a Half-Life fan, I mostly remembered it because of the cool name...
