Bio
Alfred and Judy were built by W.G. Bagnall, for special use at the Bagnall Port of Par in Cornwall, United Kingdom. The unusual design was required to cope with some extremely tight curves, and a very low bridge under the Cornish Main Line, the two locomotives are both preserved in operational conditions.

Alfred and Judy were previously kept on the Bodmin and Wenford Railway, in recent months, they made numerous trips to various heritage railways around the United Kingdom, including The Foxfield Railway, The Great Central Railway, The Tanfield Railway, The Midland Railway (The Butterley Railway), and The Beamish Railway. Alfred and Judy are now currently housed at the M Shed in Bristol, where they are sometimes chosen to give special train rides up and down the Port of Par on special weekends.

Livery
Alfred and Judy are painted in a green coat of paint, with yellow lining, although the former was once repainted in a yellow coat of paint, very similar to Bill and Ben's yellow coats of paint.
