As has been said above, the same 20' flat master can be used to produce a wide range of wagons, from the basic flat itself, through to beet, cement, asahi and more...
Have done a little with the underlay this week, hopefully will get a few days stuck into it in the coming week now, am looking forward to getting the yards down and wired so I can have a bit of a shunt
How's the intercoach coupling going to work David?
I wonder if it might be feasible to run wiring plugs/sockets under the coupling and have the rake semi-permanently coupled, to allow switchable lights and other functions?
