I have applied a couple of variable toned varnish coats and basic weathering started, light rust around wash holes or firewall door, a bit of smoke black, more will be added on the floor and walls later, before the roof is glued on.



Some of that look kinda strange in pictures (lighter spots on front wall) but very good in reality - it seems to be much closer on this picture through the window.

All this will go just very lightly, in my case the loco is pretty new, built just 2 years before WWII.
