Ernie’s Big Trip is the seventh episode of Underground Ernie. It originally aired on CBeebies on 13th June 2006.


Ernie decides to take a trip to France, but the trains fear that he's leaving them to become the manager of the French Underground. This is evidenced by Ernie learning French as well as picking up new clothes, and the trains agree that something must be done.

On the day of his departure, the trains convince their passengers to take part in a demonstration to show Ernie how much he means to them. Paris is denied entrance to the station by a militant Mr Rails waving a red flag. Ernie is confused at all this, and tells the trains he's only going on holiday, and everyone is very relieved.

At the sheds that night, the trains hope Ernie has a lovely time in France, and Bakerloo says he knew Ernie wouldn’t have left them for good, and that he wanted everyone to say a proper goodbye to him. Circle says it wasn’t goodbye, it was “au revoir” which means Ernie will be back very soon!
