Alfred and Judy are two 0-4-0 saddle tank steam locomotives. They were built by W. G. Bagnall for use at Par Docks in Cornwall, United Kingdom. The unusually low design was required to cope with extremely tight curves and a very low bridge under the Cornish Main Line. The locomotives are both preserved in operational condition on the nearby Bodmin and Wenford Railway and inspired the Reverend Wilbert Awdry to include them in The Railway Series of children's books as Bill and Ben.
