If you look closely it appears to be very short, like it was built on a wagon chassis.;)

Yes that one in the clip is a mock up of a short section of a carriage, the real thing seated 508 passengers in a four car set. The coaches were 62 feet long. (OH the joys of an old Ian Allan ABC BR Combined edition)

I have searched the web for two day but there is no page I can find where I can see the rolling stock dimensions in total for each country. Can anyone point me in the right direction please?

But that will only give an extra foot clearance and in any case doesn't cover lines into the London termini where the double-decker trains would really come in handy. It's only being done because the shipping industry is moving en masse from 8'6" high containers to high cube 9'6" types and the UK's railways are belatedly trying to catch up. Should have been done years ago.

It's rather ironic that most of the places that have the clearance to easily run double-deck passenger trains have relatively little need of them - think the US, Russia, South Africa...

am i sort of right in saying though, that you can't have double decker multiple units because the traction equipment takes up too much space and with MUs being much more popular amoung operators i doubt any double deck coaches would be ordered, even if they were within british loading gauge. notice all new 100mph or over german and french rolling stock is single decker.

I know you'll all shun me for saying this but multiple units are faster, more efficient and better for the track than locomotives and trailer coaches. -and that's another thing; double deck coaches must really rip up the track.
