Recently, I've had a few model railway thoughts on my mind; among them being that the LNER (1923-1948) lineup feels like it's been a bit stodgy and same-y for years; It's basically been the same rounds of Gresley Pacifics, B12's and a semi-random assortment of mostly GNR-designed 0-6-0 tank engines like J83's and J50's, over and over again; there's always a Mallard, and there's always a Flying Scotsman, and so on. Meantime, the other Big Four, the GWR and LMS in particular, feel like every single steam engine class they ever had, both famous and obscure, has had at least one model made of it.
It would be nice, I feel, to get some more LNER designs at some point; the "Hush-Hush" and the Thompson Pacifics are a good start, but there's a lot of workhorse designs from the Pre-Grouping era that have been overlooked. Case in point, the North-Eastern Railway Class S3 mixed traffic 4-6-0, designed by Sir Vincent Raven, and known by the LNER as the B16's:
#2378 at York
#2372, uncertain location
They were introduced on the North-Eastern Railway in 1919, and could be found all over the LNER and BR's Eastern and North-Eastern Regions, pulling assorted goods trains and handing semi-fast passenger services, including heavy holiday excursion traffic to the seaside and so on, the last one being scrapped in 1964.
As an aside, the class was divided into three subclasses; most were of the B16/1 type, which were as they were designed by Raven; but the B16/2 and B16/3 subclasses retro-fitted the engines with "LNER Group Standard" cabs, raised the running plate above the driving wheels and replaced the Stephenson's valve gear with Walscharts; the 16/2's were modified by Gresley, and thus had his conjugated valve gear, while the 16/3's were modified by Thompson, which had seperate valve gear for all three cylinders- visually though the two subclasses were indistinguishable.
