I've given the loco a test run which it does nicely. Any use looks to have been quite light as the wheels look quite clean.
The coaches are all in good condition with all buffers and couplings intact. They are NKA'super guvs' and all have different running numbers.
There is a bag of additional detailing parts included, no instructions though I'm not sure if there were any to begin with. The box is in fair condition with some shelf wear and a tear to the plastic window. If you have any questions please ask and thanks for looking!
