No, nothing special, but I did take indeed quite some extra care to have the track bed level and all the track well aligned before glueing it to the track bed (with some very liquid super glue in order to avoid having to lift up the tracks again and thereby risking mis-alignment) . Actually, the biggest pain for me was to paint the rail joiners - the (acrylic) paint just did not want to stick to the material and I did have to give it several goes.
One tip for the ballast: the T-gauge ballast is, in my view, still a bit too coarse at this scale. I ended up using, therefore, a finer, basically powder-like ballast from Koemo, a German company (
