I think that this is a prime example of Hornby's muddled thinking ...... you do really have to wonder as to which direction this company is heading, and who is making these decisions currently. Mind do which year it will appear in we wait with bated breath.
I did pose the question in the Hornby 2014 thread about ' why is this model in the Railroad Range' In my mind the actual prototype is very specialist locomotive to be in the 'play range'
Personally I am made up with the news whatever the final finish is to be as it will more than likely require added detail depending which number one chooses to model. It has to be a better start then purchasing a kit version, If the chassis is the old one then I might have to think twice though, as a comet chassis would be the possible solution. (Hope someone at Comet reads this )
