The Fuel Car was a yellow tanker introduced in the Tar Tanker and Fuel Car pack. It was later included in the Percy Express Pack, the Mavis & Fuel Car pack, and several sets. It originally featured two flammable red hazard signs on each side with SODOR FUEL written on both sides.
- When the Fuel Car was reintroduced in 2011, the tanker's design changed to reflect its appearance in the television series at that time. The words SODOR FUEL were replaced with graphics of fuel cans. The red hazard signs were also changed slightly.
- Roy Wilson's handmade prototype Fuel Car featured sticker decals.
