Detailed model of the BR Railfreight SPA low-sided, air-braked steel carrier wagon finished in Railfreight Metals sector dark gery livery.
As part of the development of the long wheelbase air braked wagons intended for fast goods trains a flat bed stake sided steel carrier wagon was produced. This proved ill-suited for many steel products, so following trials with a low-sided body 1,1000 SPA wagons were built. These have low, steel drop-door side bodies able to retain coiled products like rod/wire and featured floor bolsters suitable for loading and unloading by fork-lift truck.
As with many of the air-braked wagons there have been many subsequent modifications, both for revenue and departmental uses.
