I’m not very familiar with some of the tramway “locomotives” derived from road traction engines, but I attach some photos I took in 1976 at Britton’s Swamp, Tasmania. They show what appears to be an abandoned road traction engine, a Marshall?. (I lost a lot of sweat that day brush hooking back the blackberries to get a good look at it!)
I was assured by Mr Britton, who owned the land, it was used as a locomotive on their family timber tramway. I also seem to remember seeing an old photo of the engine in its operational state on track. I also remember being in Mr Britton’s shed inspecting the chains which drove the bogies on which the engine apparently sat. No photo I’m afraid.
On a CD, I sent a copy of these photos, with other tramway photos of other subjects, to Bruce Belbin in 2009. He was editor of LR at the time.
