Sidney is a bit of a forgetful engine. He starts his day at one location and ends up at another, not remembering how he got there! When it was his turn for repair at the Dieselworks, he was hoisted up and had his undercarriage removed. Being patient, Sidney was happy to wait...and wait...and wait. He sat there happy to pass the time with any engine that happened to be visiting.
Sidney is based on a British Rail Class 08 Diesel-Electric Shunter.
