TheCaledonian Railway264 and611 classes were0-4-0ST locomotives designed byDugald Drummond and built byNeilson and Company in 1885.^[1][2] Later examples were built atSt Rollox Works under the direction ofJohn F. McIntosh in 1895, 1900, 1902 and 1908.^[2][3][4]

These small shunters remained in long service under theLMS (who gave all Neilson saddle locomotives the power class 0F, shared by many other types) andBritish Railways, with the last of the class withdrawn in 1962.^[5][6] The two classes, sometimes referred to by the generic term "pugs", were mainly used as works shunters in the area aroundGlasgow,Scotland, often running with home-made tenders to improve their small coal capacity.^[1][7] Like most 0-4-0 tanks of the period they had outside cylinders and inside slide valves driven byStephenson valve gear. A number were later sold into private industry and several even made it as far south asCrewe, where they acted as works shunters in British Railways days.^[2] None have survived into preservation.

They are easily confused with the earlier 1882-built ex-LNER Class Y9 (NBR G Class), also designed by Dugald Drummond to a similar saddle tank design, although the 264/611 are distinguished by a taller chimney and larger circular windows.^[2] Both were originally commissioned from Drummond by Neilson & Co to a standard design and were used by North British,LNER and British Railways. One NBR Y-9 shunter (No. 42 68095) has been preserved at theBo'ness and Kinneil Railway museum.^[8]

Construction was spread over several years, and eventually totalled 34 locomotives, as follows:^[9]

All were built at the St Rollox Works of theCaledonian Railway. Orders Y1, Y22 and Y27 were placed byDugald Drummond and formed the 264 Class; the remainder were ordered byJohn F. McIntosh and formed the 611 Class.^[9]

Smokey Joe is a modelsteam locomotive based on the 264 which has been in theHornby Railways range since 1983 and has been highly popular, being regarded as a "permanent fixture" by the company.^[10] A 'starter'-level engine, it has also been the centrepiece of an eponymoustrain set in the Hornby range.^[11] The model was featured in the main Hornby Range up to 2010 and was moved into the entry-level "RailRoad" range in 2011.^[12]

Hornby's model has been in the Hornby range since 1980, initially in Caledonian Railway blue.^[13] The simplified 1983 "Smokey Joe" version omits the wire handrails that had been present on earlier variants.^[1] According to the 2011 Hornby Handbook, the model was originally launched as a "character" locomotive inspired by a Glaswegian engine which had "Smokey Joe" scrawled on its tank in chalk, an effect the model tries to replicate.^[10]

The actual number 56025 was an early 264 class built in 1890 and for its working life was primarily based atSt Rollox Works, where it was the works shunter until its withdrawal in 1960.^[14] The livery of the model is based upon the mixed traffic livery ofBritish Railways, black with red and white lining. Photographs of the original 56025 from 1955 show that instead of the graffiti, the engine had a lined saddle tank with an early British Railways "cycling lion" crest and, unlike the model, an enclosed footplate (as a works shunter, it would not have required a large quantity of coal). Most other members of the class were unlined black with an open footplate.^[2]

The model is powered by a small, 12 V "HP motor" of the same type as used inScalextric slot cars, as well as the Hornby models of theBritish Rail Class 06 andGWR 101 Class. As a result, the locomotive has drawn complaints from some hardcore railway modellers that the motor is too fast for the engine to be realistic, with poor low-speed response.^[15] As a result, it is usually regarded as a children's toy or a beginners model, rather than a model for the serious collector and modeller.^[15] It does not come withDCC capability, although can be converted.^[16]

To commemorate Hornby's anniversary a special edition of Smokey Joe was released in 2020 featuring enhanced decoration and reinstated handrails along the saddle and the rear of the cab for the first time since 1983. This edition was limited to 2000 models.^[17]
