Does anyone have any info on this new transit system at terminal 5?
The info on the web is little more than 6 trains, moving block
signalling, links
various buildings, 15 ton trains. I assume since it has signalling its
going
to be a "proper" railway unlike gatwicks transit which is just 2 trains
going up and down their own dedicated tracks. Is it circular? How deep
are the tunnels? Will it be in the tube/hex station or will it have its
own
station? Anyone know?
