Now clearly if I can refer to a pug as perfectly formed I'm not talking about the weird looking breed of dog! In Scotland the term pug was used to refer to any small shunting locomotive, but in England when used to describe a steam engine it usually refers to a class of 0-4-0ST originally built by the Lancashire and Yorkshire Railway (L&YR).
These small shunting locomotives were designed by John Aspinall to work in confined areas, such as docks, where larger engines were unable to cope with the tight curves etc. The first of the class appeared in 1891 and 57 were eventually built with the last batch entering service in 1910. The last Pug was withdrawn from service in 1964. This time range runs right through the period I'd been thinking about modelling (see this previous post) and so seemed like an ideal engine to acquire.

It's a wonderful model, that really is small compared to anything else I own -- it's just 8.5cm long, about the same length as the 12 ton coal waggon I'm building. In fact it's so small that unfortunately the motor can be seen in the cab as Hornby were unable to fit it within the boiler like they do with most of their models. Still, I really like it and I can imagine building a goods yard or dock side area into a layout just to have a good reason to run it frequently.
