Thomas & Friends (1984)

S16E01 Race To The Rescue

Flynn, the fire engine of Sodor Island, has been modified to travel both on roads and train tracks. As he sets off down the road, his nerves cause his wheels to shake. Charlie passes by and teases him, making Flynn feel embarrassed. Soon after, Rocky informs Flynn that Sir Topham Hatt's shed is ablaze. Eager to help, Flynn chooses to take the tracks instead of the quicker road route, determined not to be seen as a "big red wobble on wheels."
