Uncharitable interpretation of TFA. “independently moving wagons” are different from a series of linked wagons that all have to leave the terminus at the same time, travel together, and arrive together. This idea would allow independently moving wagons to be dispatched as required from multiple destinations, share the line with others in very close proximity, and break away seamlessly to their different destinations.
