From Miniature to BIG

Hornby have a very clever design that simply works, they have been doing coaches with this shared bogie arrangement since the 80's (or was it the 90's - I don't remember) when it was introduced in the Eurostar trains they modelled.  The big difference here is that they have supplied the accessories to make a connecting corridor etc... between coaches as well.  These have been long in the design/planning stage so I would be surprised if they have messed up the connectors now.  Having said that, they are probably restricted to the wider arc curves rather than the smaller/sharper curves that are available, but this is not unusual as often some of the bigger pacific locomotives are limited to the larger radius curves anyway.  As the normal locomotive for these coaches is the big coronation class pacific that is almost a certainty.
