The Sad Story of Henry - S1-E3
Audio problem: When James is about to puff away from Henry's Tunnel, if you listen closely, James is heard puffing before he has even left. (00:01:00)
Other mistake: When Thomas is uncoupled from Annie and Clarabell he has Percy's face.
Other mistake: At the start Gordon's buffers are crooked.
Continuity mistake: James and Edward are on the mainline at first, but then they overrun the platform at Dryaw station, which is on Thomas' branch line.
Audio problem: In the 1992 "Thomas Gets Tricked" VHS release, the music stops and a man's voice says, "Look out for the train!" when Thomas climbs up Gordon's Hill. The voice can still be heard in the 1995 release, but the music does not stop.
