Phil, your 1:12 gradient is pretty close to my max 1:10.
I found that whilst steam locos could get themselves up and down in a well mannered way, it was when there was a load behind them, such as a few cars, that the problems arose.
Diesels, especially traction tyred ones, had less problems but still needed multi heading to haul a decent size train up the gradient and to also be able to hold the string of cars back when going down the descent.
Besides always multiple heading trains I got around to motorising some rolling stock to 'invisibly help' a single loco to be able to tackle the slope.

Seen as we all like photos on here, I have taken advantage of the morning sun. Its nice to get some bright photos of the line for once.
Last batch of ''free'' road side rocks to help blend the new spur into the garden environment. It does not look quite so obvious now. So storm Frank permitting I will get the rocks pointed in above the tunnel and then paint the tunnel mouths with my masonry paint.
Another building made. Looks suitably creepy for a cabin deep in the woods. Reminds me of the film, Wrong Turn!
