On heavy unfitted coal trains form the Welsh Valleys to London, 6 wheels and 8 tons of extra weight were required to produce sufficient braking force to keep the train under control. Easy to assemble from the correctly coloured injection moulded components (no painting necessary). Kits include Transfers. Buffers are sprung and 3-link couplings are included on all models, while the BR wagons also feature working axlebox springs and moveable brake levers. Fine scale metal tyred wheels on pin-point axles supplied, spoked for the GWR wagons or 3-hole disc for the BR types. Fully illustrated instructions included.
