Given they are supposed to arrive in July, he can't have had enough time to do anything. These units have probably been in production for sometime, so I think you will have to reconcile yourself to the fact they are likely to be same standard as those already delivered. In any case, Hornbys record on amending existing products is not very good, but we can hope that they are picking up on the comments for future models. We can be heartened that Roger Canham does seem to be listening and taking action (ref lower prices thread)
