S02E15: Better Late Than Never

The viaduct is being repaired on the Main Line. The Fat Controller doesn't want to close the railway whilst the repairs are being done, and so orders the mainliners to go slowly when crossing it. This delays them with their journey to Thomas, which makes him late to meet with Bertie. Altogether, Thomas becomes very annoyed; until the day comes when he realises that being late isn't such a bad thing after all.
