Private Engine Down

Private Engine Down
This is the 42nd episode of the fourth season

Plot
After going too fast and running into works on the tracks, Spencer is put out of action. The other engines try time and time again to prove they are worthy of filling his spot until he returns. Eventually someone is elected to take his place. References to Gabby & The Difficult Trucks, Little Royal Engines and Spencer's Grand Race are made. Later on, the engines all get angry and band together to get Spencer from the mainland works, but when they've arrived at Henry's tunnel, they fear what is inside. It's Spencer in his Halloween costume!
