Slow Stephen / Two Wheels Good

S19, E107: Slow Stephen: Stephen is the oldest engine on the Island of Sodor and people love to see him, so sometimes he makes special journeys round the island. He's still called the Rocket, though he's much slower than the other engines. Sometimes they have to slow down for him, which Gordon in particular doesn't like. But it's because Stephen travels so slowly that he notices that the Suspension Bridge is damaged and manages to alert the other engines in time to avoid a disaster! Two Wheels Good: Bertie, Thomas and Spencer get into a debate about how many wheels is best. Bertie has four wheels, Thomas has six and Spencer is very proud of his twelve. But when Spencer breaks down while taking the Duke and Duchess to Callan Castle, Thomas must transport his passengers instead. Then Thomas finds the track blocked and Bertie takes over. And when Bertie has a flat tyre who should turn up, but the Thin Controller on his bicycle. Surely the Duke and Duchess can't ride to Callan Castle on his bike! Luckily, the Thin Controller has a better idea about how to help.
