The engine does not seem to based on any real-life steam locomotive, but it is possibly a well-tank engine because there are no water tanks mounted on either side of the engine's boiler or above it.
Livery and Features
The engine's body work and wheels are painted in red with white stripes with a maroon smoke box and funnel. It has brass tubing, fittings, buffers and a coupling hook. There is also a bell at the back of the dome, which is rare for most locomotives in the UK. The engine has a large lamp mounted on top of its smoke box and sliding doors on each side of its driving cab. It's front bufferbeam is curved, which gives it a streamlined look.
The carriage is painted in a two-toned red and white.
- There is also a wooden flatbed truck at the rear of the train which can come in handy for the firefighters, when they need to bring Mercury along for mountain rescues. Bessie also uses that flatbed truck if the Pontypandy Flyer is already up in the mountains or if Gareth is absent.
- The engine's whistle sound is exactly the same one used for Spencer in Thomas & Friends (another HiT Entertainment series that several of the Fireman Sam voice actors and writers work on).
