The Rails version will never sell in model shops ,tourist railway shops , on Ebay except used or possibly for gain,etc .The Hornby will sell all over the world in shops.Maybe Dapol will take it over after a few years. OK The NRM will get it and some hot marketing will mean it will sell but as I said earlier Hornby are the train set of England .A few lost or incorrect details wont stop it selling out there.I was on the North Norfolk when they had the little Terrier (forgotten which one ,getting old ) chugging up and down ,a total delight .I was wearing a photographers bib and a guy came up and asked if Hornby made a model and where he could get it .Nuff said .
