The Caledonian 'Pug,' No. 272, as delivered to the Sumtown Tramway Company in January of 2012. A small yet sprightly 0-4-0ST, this engine is capable of the shunting turns in the quarry yards with the most ease.

A side view of the locomotive, showing its diminuitive shape and proportions. This locomotive, though appearing rather basic and childish, is actually quite handsome and iconic in the flesh, with its Caledonian livery picked out well and its shape marked out well against the background.

The locomotive's tanks, outlining the safety valves and the branding of the Caledonian letters - simple, yet effective.

The rear profile of the locomotive, outlining its cab and numberplate of No.272. Lining out is done well here, and the cab is quite spacious for crews - the footplate being open and extended back a fair ways.

A photograph of the interior of the cab, outlining the various levers and controls. For a small locomotive, the cab is actually more complex than would previously be determined - the footplate crews had to spend a few extra days learning and memorizing the cab configuration, it being a bit more complex than that of the other locomotives, bar the ALCO switcher.

The front profile of the locomotive, showing its iconic face. Diminuitive yet powerful, the Caledonian Class 0F has proven its worth already, and will continue to do so in the future.
