I have added a new collection featuring The S.D. Holden B12 (GER Class S69 / "1500"s) 4-6-0s

The Great Eastern Railway (GER) Class S69, also known as 1500 Class, and later classified B12 by the London and North Eastern Railway (LNER) is a class of 4-6-0 steam locomotive designed to haul express passenger trains from London Liverpool Street station along the Great Eastern Main Line.[1] Originally they were designed by S. D. Holden, but were much rebuilt, resulting in several subclasses.Seventy-one S69 locomotives were built by the GER between 1911 and 1921 and numbered 1500–1570. A further 10 locomotives were built by Beyer, Peacock & Co for the LNER in 1928 and numbered 8571–8580.[2] From 1948 the British Railways numbers were 61500–61580 (with gaps).

This first collection features the locos in GER days

During the 1920s, many of the B12s participated in Gresley's Feed Water Heater experiments. These attempted to recover waste heat by using the exhaust steam to pre-heat the water before it entered the boiler.
