My two loves in modeling are S scale and the 1870's. Glad I finally realized it is possible to do both. S is the perfect layout scale. All those grossly oversize scenery textures that plague HO layouts are the right size for S and all those texture layers required by O scale can be omitted.
Have made progress in converting the On30 layout to Sn3.5
Got the cribbing in for the pump shed and boiler. That is our 4-4-0 merge with a S scale cab under construction

Narrowed the roads and installed the new tunnel portal

It is nice to be over my "layout block" and working on the layout. I have stared at the layout for three years and could never get started on the O scale oil transfer facility.
