Our reference book* has quite a good photo of the loading dock with lowmac trucks carrying lorries in the adjacent sidings.
The loading dock is unusual in so far as the raised platform on the right of the siding is very narrow and of no use for loading; on the left is a retaining wall instead of a platform. The retaining wall seems to be there to stop loose materials falling on to the track. The buffer stop is simply a stack of track sleepers.
There needs to be some way of loading lorries onto lowmacs. My initial thought was that the lorries were driven up a ramp over the buffer stop (the top of which appears to be only about 6 inches above ground level) but the model has shown that there may not have been enough turning space there to line a lorry up with the truck.
Another mystery is the long channel between two of the sidings (there is also another one further along and out of view in this photo). Whilst they are clearly visible in photos of this area it is not known what purpose they served. The two ends look like metal square hoops with boarding between them.
This triangular yard between the black shed and sidings was covered in various materials and this will be populated with such in phase 3 of the project. Beyond the shed is a dump of loose waste material that has already been modelled.
In latter years this entire triangular area is known to have been a dump for waste from vehicle manufacture and that may have always been the case, which to some extent makes sense of the retaining wall.
