Detailed model of the BR SPA low-sided, air-braked steel carrier wagon in use by the engineers departments as a materials carrier and coded ZAA PIKE and painted in the engineers grey and yellow Dutch 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.
