A client asked me to build a representative example of a Great Western permanent way train and this is the result.
These two pictures (unfortunately my photographing diorama is not large enough to do it in one take) are of a whole train built for a client who wanted a Great Western Permanent Way train for both display and running.  It consists of a Tool Van, a Signal Post Wagon, an ex Cambrian 2 Plank Open, a couple of Ballast/Spoil wagons and a Permanent Way Toad.  All bar the 2 Plank Open are in ex works condition but will probably be suitably weathered in due course.
They are all compensated and with replaced self-contained buffers - except the 2 Plank Open - and WEP couplings.  You can see most of them in detail by clicking on the appropriate links above.
