The Bachmann OO Gauge 33-901B 45 Tonne Weltrol Bogie Well Wagon in GR Grey x 2 is a DC-powered model train accessory designed for the British Rail corporate livery. This ready-to-go pre-built plastic freight wagon in 1:76 scale features an analogue control system and is part of the Two-Rail System. The grey-coloured wagon represents Era 9 - Post privatisation (1995 onwards) and is a collectable item perfect for transportation-themed model railway enthusiasts. Made by Bachmann in China, this item is a great addition to any railway layout. These are from my late father's collection and was stored in the attic. They are Unboxed. buffers and couplers intact. see photos.
