Toby's Discovery

"Ghosts don't work day shifts."

- Toby's driver

Toby's Discovery is the fourteenth episode of the fifth season.

Plot
The young Hatts make a sandcastle modelled on one in the heart of Sodor and the intrigued Fat Controller asks Toby to take him to find it. Toby finds the castle, and then visits a run-down mine located on the same map as the castle. The mines are re-opened, but Toby is spooked by Thomas' tale of the "Old Warrior" who hunts in the mines during the night. Toby is horrified to be put on guard duty at the mines and meets the "Old Warrior", but discovers the ghost is really a narrow gauge engine named Bertram.

Goofs

 * When Toby is at the fishing village, Henrietta's roof is raised.
 * When Toby stops at the signalbox, Toby and Oliver's themes are heard playing at the same time.

 * At the end of Toby's first-person view while travelling along, the rails stop at a dead end.
 * As Thomas reverses into the mine, a bug crawls across the sandy spot to his right.
 * When he is discovered, Bertram appears to be sitting on grass, but he was heard puffing (very loudly for a narrow gauge engine).
 * The signalman changes appearance between the time Toby first meets him and the time when Toby finds Bertram.
 * The old map shows that to get to the castle and the mine beyond the signalbox is to take the right track at the junction, but Toby takes the left track at that junction!
