Episode Title:
No Steam Without Coal.
Episode Description:
Bill and Ben run out of coal during a shortage at Clay Pits and have to rely on Timothy, who runs on oil, to help them out. It was Ben's fault to not get the coal as planned, and he told Marion that it was probably enough coal in the hopper. But Marion was concerned about this, and it later became something out of chaos. Eventually Timothy gets the coal, and Bill and Ben agree that oil going engines have their uses, especially when they're out of "coal".
