Description
Cold weather stops a delivery of coal arriving on Sodor, so the Fat Controller orders all engines to stay in their sheds. Thomas, however, thinks he has enough coal for one more run, but he gets stranded in the snow whilst the diesels take over the steam engine's jobs to keep the railway running.
