You also make a valid point, it's horses for courses. If Hornby had just produced a basic rail road model and a super detail version with all the bells and whistles, they might have lost a lot of sales to people who don't want Rail Road, but are not willing to go above £120 mark.
I think this has been suggested somewhere else, but maybe they need three versions of the model, Railroad, mid range and top of the range? I wonder how feasable that would be?
Yesterday I had a look at the Wishlist Poll. The Turbomotive and the W1 were on the list. If Hornby do end up producing one of these loco's, I do hope they give it the full bells and whistles treatment.
I also hope they return to Cock Of The North at some point and produce a new bells and whistles version.
