A former LSWR engine, Katie was privately purchased many years before and spent many more in storage under restoration.

Unfortunately, her restoration was cut short when her owner went bankrupt and she was forced to be put up for sale, fortunately though, she was purchased by a branch of the Oakham Road Preservation Society and was then fully restored and now works on the Butser Island Extention with Strowdley.

Katie is based on a LSWR Class O2.
