 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.The actual number 56025 was an early 264 class built in 1890 and for its working life was primarily based at St. Rollox railway works, where it was the works shunter until its withdrawal in 1960.The livery of the model is based upon the mixed traffic livery of British Railways, black with red and white lining.
