Paxton's Busy Day


Paxton is a BR Class 08 on the North Western Railroad. Unlike Diesel he has a lime stripe running from his cab all the way around. He is usually at the Quarry with Henry, James, Toby, and Mavis, but he will collect specials on order of The Fat Controller. However Norman and Sidney get tired of hearing him talk about his special and they consider it boasting. One day, Paxton is very excited, The Fat Controller has asked him to collect all new can of Oil. He tells that to Norman and Sidney and after he leaves, Norman whispers something to Sidney. They were going to make his job a Failure, so he would have NOTHING to boast at the Sheds. As, Paxton is Sodor's slowest engine... Diesel to be exact, Norman and Sidney overtake him. When Paxton arrives at the Quarry, Mavis is strugling with 20 slate trucks. Norman and Sidney had shunted these. But as slow as Paxton is, he quite strong and promises to deliver the trucks to the Docks and then from there he'll collect the Oil. Mavis agrees and Paxton sets off. Norman and Sidney all the while are shunting trucks at Maron, they laugh. Meanwhile at the Hill, Paxton was having trouble, quickly contacted the station. Paxton had an idea and explained quickly instructions. Paxton and the Break Van swerved into a siding, but the trucks crashed into Norman and Sidney. The Fat Controller saw it , but wasn't cross, Diesel 10, Den, and Dart had told him their plan. Later, after Rocky lifted them onto the Tracks, Paxton and Mavis pushed them home, hoping next time Paxton has a special, they won't plan a plan.
