Most of the outer loop is ballasted - just have one outstanding grade crossing to complete (and that's really more about getting the road and grade crossing beams installed than anything else.
I should write that I am done installing the ballast. What remains now is more properly classed as 'clean up'. Going back over my earlier work - especially the first loop that I did - I see that I did a pretty bad job. So bad that in some cases the ballast is impacting the operation of the trains. So....I'll need to go over each rail and scape off excess ballast. It'll give me a change to check the rails as well - there are still a couple of spots that are giving me problems like uncoupling and occasional derailments.
I'm starting on some of the landscape now as well. There are some very simple areas that can be knocked out quickly. (bare stony ground with scrub vegetation). I'm experimenting with the grassy areas. Most of my prior work was on much smaller areas and in much smaller scales. I need to adapt to the level of detail S gauge trains require.
