Description
Something else we found at Crewe was British Rail 9F number 92203 "Black Prince", but as my full shots of the engine kind of sucked (the sun was in the wrong place, and being Crewe this could only be expected) I thought I'd use it as an opportunity to talk about the wheel arrangement of the 9F.

Oddly for railways in the UK, the Class 9F was a 2.10.0, or 1E, a type of wheel arrangement which was only started by the War Department during WW2, the first 2.10.0 being a variant of the Austerity 2.8.0 designed for lightly built railways. The Standard Class 9F however was a later design by British Railways, featuring a flangeless central driving wheel to allow for the locomotive to negotiate various tighter curves, and a high power and rail adhesion rate to allow for a greater flexibility of the fleet. In total 251 locomotives were built, of which 92220 "Evening Star" was the last steam locomotive ever produced by British Railways. 92203 also holds the record for hauling the heaviest freight train in Britain, at 2198 tonnes, set in September 1982 at Foster Yeoman's Tor Works.
