C41 BR SEA URCHIN (ZCA) BALLAST WAGON

These are a conversion of OBAs, SPAs and VDAs. This kit is for the OBA conversion in the early 1990's with 5 vertical side stanchions (There are others with 6). The only remaining part of the OBA body appears to be the end stanchions, the rest being replaced with new steel parts. The earliest rebuilds had flat-topped sides and ends. Later ones had a triangular shaped top and heavier cross bar on the ends. This is the type that the kit is based on, however, the triangular part can be filed off to make the earlier type. The end cross bar will also need filing back on its vertical face so that it projects about 0.5mm less than the vertical stanchions. The ZCA Seahorse/Urchin wagons were used to carry new ballast or sometimes spoil/spent ballast. The wagons have carried a variety of liveries.
