Northeast England during the pre-grouping steam era.
Shildon yard was a busy coal yard even before raven electified the lines east from there to Newport on the River Tees but coal and coke were not the only things handled there. The N.E.R. had a wagonworks at Shildon, which dated back to the earliest days of the Stockton & Darlington Railway.
While Worsdell C Class 0-6-0 1569 stands with her train in the yard prior to departure, a 290 Class 0-6-0T pulls a rake of newly painted 30 Ton Ironstone hoppers in to the yard, likely from the wagonworks following overhaul. Once back in traffic on the Cleveland - Workingon ore runs they will not stay clean for long.
The more normal state of the 30 Ton Ironstone wagons. These steel hoppers were well ahead of their time, when most of the N.E.R.'s wagon stock was wooden. The LNER's steel 20 Ton hoppers are thirty years in the future from this screenshot's setting. The wagons also have rolling gear, which was meant to reduce friction (the wheels at the wagon sides). Unfortunately, while it seemd a good idea in theory, also being tried with the P8 21 Ton Coal Hopper, the extra capital cost, coupled with the extra maintenance costs, plus clogging from coal and ore dust, did not realise its theoretical potential. The P8s all eventually became ordinary 20 Ton P7s when the gear was removed, while the Ironstone Hoppers did not change diagram number when they lost their gear.
Shildon Signal Box is in the distance. The overbridge remains in existence, but today there are just two main through tracks, the running lines of the Bishop Auckland branch. The line still snakes its way through where the yard used to be, somewhat the same as the line between Middlesbrough and Thornaby does, where Tees yard used to be. Quite why the railway has not done anything to straighten the routes through the acres of weeds and shorten the route a little is unknown to me. In the case of Shildon they've only had sixty years to think on it, while Tees yard is a rather shorter twenty years or so.
Today, where the wagons are standing is the site of the National Railway Museum's LOCOMOTION outpost.
