I finally have some pics posted of the work in progress, from the beginning up until almost the present:

I also knocked out a crude 3D model so you can get a rough idea of what I have in mind. This is the first pic in the album. The second is a simple overhead view of the model, showing the basic trackplan. No spurs or sidings, and some of the route is a bit speculative at this point. Especially the upper levels of track, which may differ from the plan once I get that part of the hill cut and shaped.
I took eight days off from doing any heavy work, such as lifting or digging, to give my back a chance to heal. It’s still not up to par but is holding up. Yesterday I collected a load of rocks and today I did a little bit of light digging, rock placement, etc.
During the downtime, I laid and ballasted a few feet of track leading into the first tunnel. Today I finished a small trestle too. No pics of that yet but you can see the wooden abutment for it in the pic of the ballasted track.
Tomorrow I may try casting some concrete abutments.
