Does anyone know of S scale trolleys available ? PA heritage has them but are expensive. Can O or O27 scale be used suitably on an S layout ?
You could use O27, but it will probably be a little oversized. O27 is around 1/55 scale, but usually not scaled down the same in all 3 dimensions. Industrial Rail now by Atlas I think is still 1/55 so it’s a little oversized as well. Whether that’s close enough is up to you. I think PA Heritage is also oversized since they used Corgi bodies for both S and O
