It's the Hatley Bowls Club Outing. Cecil Parkin is all dressed for the occasion, having posted Jack Skinner to stay behind on duty. However, Mr Orkindale insists that Jack comes instead. He lies that Jack is a star bowler, but really it is because he buys his round. Left on station duty while Jack takes his place on the outing, Mr Parkin soon puts aside his indignation, when he realises that May has been accidentally left on the station as well. Unfortunately, she's not so thrilled about it.

After a shaky training day on the "Flamin' new diesels", Arnold suspects he's going to get the push and takes drastic steps to make sure he doesn't. May and Jack are equally as worried about whether now is the right time for another baby.

Hatley station is 100 years old, and a celebration is planned including a photo and news article. Ralph drives the train to a successful end and the staff dress in period clothing, after which a great street party and a not so surprising reaction to the vegetarian food ends the series with a trumpeting farewell.
