Theres an unloading facility darn sarf that I am going to sort of copy. LaFarge operates out of a number of depots around the country. The one I am talking about is just North of Radlett in Hartfordshire. The railway line in the depot is a circle with a short connection to the adjacent Midland Main Line. Trains enter and go round in an anticlockwise direction towards the unloader.The unloader is far enough away from the entrance point to get the train in clear before the train has to unload( Be silly to block the main line whilst unloading). I think, but am not sure, that the wagons have to be unloaded automatically like a coal Merry go round wagon. The wagons are unloaded as the train continues back round to the now normalised entry point. When the train is m/t, the loco unhooks and continues round a/c/w, alone, to meet the rear of the train. It is hooked on the rear(now front) and exits the yard in a clockwise direction.
A brilliantly simple solution for train operation. You can clearly see this on Google maps. Type in Radlett, find the MML and head north for a mile or two.
I'm going to do a loader with some R1s, Bachmann Davenport and some HLW/Bachmann side tippers(manual unloading!). Unsure about the building for the loader yet but it will come no doubt. Plywood painted black probably! Not very good at buildings. Alternatively, does anyone know of a suitable building for a trainloader supplied by a conveyer?
