I purchased these kits from ‘S Kits’ some time ago. They are superb and went together very well, my only problem was I only purchased three instead of at least six. The kits are resin bodies/chassis with whitemetal bogies and buffers etc.

As these wagons were converted from existing wagons, there are several variations, especially the bogies. As Railtrack was a short-lived part of rail  history, they later moved to other duties. I modelled mine when owned by wagon leasing company ‘CAIB’
