A Big Day for Thomas

"A Big Day for Thomas" is the third episode of the first season.

Plot
Thomas is getting bored, working at the station shunting coaches all day. He complains about it, and annoys the other engines. But one morning Henry isn't feeling well, and Thomas is the only engine available to pull his train. He is excited, and becomes impatient - so much so that he leaves his coaches behind. Soon, a signalman stops him, and Thomas sadly goes back to collect the train. But the other engines teased him a lot about it, and he learned not to be so impatient with coaches.
