Alf (full name Alfred) is a J52 saddle tank engine who is the first privately preserved steam engine.
Alf was built in 1901 at Sharp Stewart & Co. He was retired from regular service in 1959 and was bought by Captain Bill Smith. According to Wensley, he now runs brakevan railtours all over the country, and he is given everything that a steam engine needs.
Alf is based on the real No. 1247, a GNR J13/LNER J52 0-6-0ST. It is currently in the National Collection in York as of 1980.
Alf is currently painted in Great Northern apple green.
