Well my last question was obviously too hard so I will wait to see what archives comes up with.Yes, there was a dead end siding with flexible pipes that disappeared into the ground for pneumatic unloading. It was usually occupied by two to four BC wagons, although the odd TB also made an appearance. I do have photos that show the area, but they aren't mine to distribute publicly.
In the meantime a simpler question. I can see in some photos that there was at one time what looks like a concrete batch plant near the Hobart Station carriage roads (not the batch plant that used to be behind the Royal Engineer's Building). Does anyone have any photos of this and can anyone please tell me if it was serviced by a rail siding for bulk cement wagons?
