- Samson Class 2-4-0 Locomotive Class
- A class of 90 2-4-0 engines with 6ft 0in driving wheels built for secondary duties under Ramsbottom and Webb from 1863 to 1879. Reputedly the first passenger engines with coupled wheels. It has the usual Ramsbottom features: the fancy chimney top, safety valves, horizontal smoke box door, slotted splashers, no brakes on the engine and no cab. The coupling rods are of the early Ramsbottom type, with forked ends having wedge adjustment and cottered fastenings. 80 replaced by ‘Small Jumbos’ in 1890’s, the others continuing for 20 years in engineer department use.
- Side Tank Coal Locomotive Class
- The official designation of Webb’s ”Coal Tank”.
- Small Bloomer 2-2-2 Locomotive Class
- In 1834 the ‘ Small Bloomer’ were introduced. The were basically similar to the ‘Large Bloomer’ but had smaller boiler and smaller driving wheels 6ft 6in, instead of 7ft. See also Extra Large Bloomer, Large Bloomer, and Bloomer.
- Small Jumbo 2-4-0 Locomotive Class
- Ramsbottom’s Samson class engines were replaced in the 1890s by engines which were outwardly of similar appearance to the ‘Improved Precedents’ or ‘Jumbos’ which had been introduced by Webb in 1887. The replaced Samsons had smaller 6ft driving wheels and were thus colloquially known as the ‘Small Jumbos’. Small Jumbos were also sometimes known as ‘Whitworth’ or ‘Waterloo’ class, after early members of the class.
- Special ‘DX’ 0-6-0 Locomotive Class
- In April 1881 Mr. Webb rebuilt ‘DX’ No.460 with a new 140 psi boiler of the same kind fitted to the ‘17in Coal Engines’. No definite information on the origin of the term ‘Special’ seems to be available, but was perhaps only used once the engines were vacuum-fitted to denote those specially fitted to work Passenger trains.
- Special Tank 0-6-0T Locomotive Class
- This was Ramsbottom’s last design, which was in effect a saddle Tank version of the ‘DX’ for shunting, with the same cylinders and wheelbase but slightly smaller wheels and boiler. Two of the class were modified with rectangular saddle tanks and condensing apparatus for use in Wapping tunnel, Liverpool. From 1895 they were used on the American Special boat trains through Waterloo and Victoria tunnels between Edge Hill and Riverside, Liverpool, for this duty they were painted in fully lined livery, and named “EUSTON” and “LIVERPOOL”
- Super D 0-8-0 Locomotive Class
- Colloquial name applied to the LNWR’s G1 class of super heated 0-8-0 goods engine, and later to all such engines including the G2 and G2A classes. Super was an abbreviation of “Superheated”.
- Swamis Locomotive Class
- Nickname for “B” Locomotive class; swamis were oriental magicians and illusionists popular as entertainers in the late nineteenth century, who always finished their acts by disappearing in a cloud of smoke…
