What is the market like for K27 and 2-6-6-2 locomotives in their original boxes which have never been used before?
It is a small niche market, but in a place like this, it is still fairly strong.
Don't expect to get anything like MSRP original new pricing however!
check ebay, the only indicator unless you want to track other auctions..
(TRAINZ.com will indicate last selling price)
