Talk:4-2-2

Steam sanding?
Did Stirling use steam sanding on his GNR Stirling 4-2-2 in the 1870s (as suggested here) or was that introduced later (Holt, Midland, 1886), inspiring Johnson to build his later singles, after singles (including Stirling's) were otherwise considered obsolete?

 * The Stirling eight-footers were built with gravity sanding; steam sanding was substituted from 1886 . By that date, 41 were in service, and no. 775 (built Jan 1887) was the first of the class to be built with steam sanding instead of gravity ; we can probably assume that nos 776-8 (built Mar-Nov 1887) and 1001-1008 (1893-95) also had steam sanding from new. -- Red rose64 (talk) 16:43, 1 December 2011 (UTC)
 * Thanks, that makes sense. Looks like some change is needed here. Andy Dingley (talk) 16:50, 1 December 2011 (UTC)
