Old Reliable Edward Thomas the Tank Engine & Friends : Season 18 Episode 1

The bigger engines tease Edward for being old and unreliable, especially Gordon. But when Gordon sees some red trousers blowing by the tracks, he mistakes them for a red danger flag and stops, ending up stuck on Gordon's Hill. Edward has to come and give him a push, but Gordon does not even say thank you, so Thomas and Edward decide to teach him a lesson.
