English: As of the 1870s, the need to transport passengers between the suburbs and the London area intensified. To ensure efficient yet economical rail service, British engineer William Stroudley designed rail passenger equipment comprised of compact locomotives and smaller passenger cars. The most noteworthy example was the A1 “Terrier.” This locomotive class was based on a 0-6-0T type and quickly became popular with commuters. Some 50 or so locomotives were built and operated on the lines to the south and east of London.

Between 1911 and 1913, 17 locomotives were modified to the specifications of Douglas Earle Marsh. The main modification was the installation of a modern boiler, both longer and more powerful. This altered the appearance of the small locomotive and the modified class was renamed A1X. The “Waddon” belonged to this modified class.

The unserviceable “Waddon” was acquired in 1963 to illustrate the differences between European and North-American locomotives. It was recently cosmetically restored by a group of canadians railfans of british extraction. Nine other A1Xs are preserved in England, six of which are in operating condition.

All the information used with the pictures was taken from information at the Canadian Railway Museum Site.
