"Old Stuck-Up", so nicknamed by James, is a usally nice diesel. but is sometimes vein but helps the other engines alot
Old Stuck-Up was built at December 9, 1960.
In 1983, BoCo was to show a visiting diesel around, but when he saw steam engines in the shed he refused to go further and insulted the railway for keeping them in service. A furious James bestowed upon him the nickname "Old Stuck-Up".
The next day, Old Stuck-Up was about to leave when he remembered he needed refueling. He attempted to use BoCo and Bear's part of the shed to be refuelled and cleaned, but slid on cleaning fluid on the rails and crashed into the back of the shed. He will by scraped with Irma and the diesel railcar for helping Irma and The diesel railcar for kill Mr. Percival. Owen won't know that Mr. Percival died and ask Merrick who will be crying for adness Old Stuck-Up may call Merrick an idiot.
Old Stuck-Up is rude and arrogant, as seems to be the norm with visiting diesels, and believes that steam power is subpar to diesel. He is friends with Iron 'Arry, Iron Bert, Splatter, Dodge, Diesel 10, and his brother The Diesel. He is enemies with James, BoCo, and The Works Diesel.
Old Stuck-Up is based on a BR Class 40 1Co-Co1. He carries the numbers 40125 and D325.
Old Stuck-Up is painted in a British Rail "Rail Blue" livery with yellow warning panels.
