Peter is an LMS Stanier 8F steam engine who was placed in the Ballahoo Tunnel for the Strategic Steam reserve.
Peter had been placed in the Ballahoo Tunnel as part of a pilot program to test the feasibility of having a reserve fleet of steam locomotives during the Cold War, when an electromagnetic pulse from nuclear attacks could have disabled diesels. The program was scrapped when it was found that the amount of maintenance to keep the fleet in working order at all times would be too much. Emily Helen Hatt, along with her brother Charlie Hatt, discovered Peter in 1996 and he was bought & restored by the North West Railway.
It was revealed in The Missing Engine that his BR number was 48102.
- Season 1 STMY - A Change of Scene (cameo), Tornado, The Missing Engine, Separation Anxiety, Last Laugh and Taking Care of Christmas
- Season 2 STMY - Swan Song, Arrogance (cameo), Engines of All Trades (cameo), The Thin Clergyman, Caden, Troublesome Trucks (cameo), The Devious Way and Endgame (stock footage only)
- Originally, Peter was to be called Colin, and Colin, the Wellsworth and Suddery Railway engine, was to be called Peter. These names were swapped when WildNorWester realised that the nickname 'Big Pete' would suit the Stanier 8F character better.
- Peter debuted in Locomotives and Legends, which was a written volume by WildNorWester that takes place between Season 5 of Sodor: The Early Years and Season 1 of Sodor: The Modern Years. Therefore, he was never introduced in an episode of the series itself.
- Peter uses a combination of Henry and Duck's faces for his own faces.
- WildNorWester revealed on his DeviantArt account that Peter's model is a modified version of Henry's.
- When Peter received a new model for Season 2 STMY, the color of his running plate was changed from white to black. The running plate itself was apparently shortened on the sides.
- He is good friends with Caden, the shunter at Barrow.
- Morbidly, the real 48102 was withdrawn in August 1965 and scrapped the following year in Febuary.
