This is where I'm up to - body painted, initial weathering applied but with rusty lower level highlights to come. A simple plastikard insert to hold a ballast load is ready for its ballast to be glued on and the tie down cleats also need adding once the yellow paint on them is dry - holes are drilled ready.
Then all it needs are some transfers! Bogies are done and wait for final varnishing before I reattach them.
I expect tomorrow to be able to paint the track on the new extension piece after cleaning any stray ballast off the rail faces.
