... Or perhaps Hornby were right...
Let's be frank, this is probably the case. Personally (and as the person who started the Railway Modeller comment piece thread in the 3mm scale section of this website a few weeks ago) I would LOVE to see one of the major manufacturers 'go for' TT, whether that is at 3mm scale or 1:120. However nothing I have subsequently read or heard has convinced by that it is anything more than a pipe-dream to be honest.
I think it is sad, as the scale seems to have so many practical benefits, but clearly a commercial reality.
'SHOULD Hornby re-introduce TT?' I'd love them too and would be a willing 'scale-hopper' overnight!
'WILL Hornby re-introduce TT?' Quite frankly no. They have considered it and rejected it. I don't know whether there is anything more to say!!
