A/C will not be appearing on deep level tubes, but there is an ongoing project to introduce tunnel cooling.

So the story in the papers the other day about a 14 mile test track in a former Asfordby mine in Melton Mowbray, Leicestershire, is a load of twaddle then? They certainly gave the impression, as only the media do best, that all new tube trains will be air conditioned and will be tested there first.

Are they perhaps half right, in that S stocks will be tested there?

Testing for 'S' Stock will take place at Old Dalby and London. I suspect that the track will also see a fair amount of 09ts too. As you know, 'S' will feature air con whilst 09ts has forced air.

I think that answers my question ;D ;D ;D ;D

Actually Chris M's idea has been applied in Kuala Lumpur. There is this LRT system called STAR (Sistem Transit Aliran Ringan) and during off peak it runs four-car trains, but during the peaks it operates six-car trains. The two variants are shown below. The trains consist of two car units. It works like C stock, except that the centre unit has no cab. Off peak, the centre unit is removed.

Key
- is articulation walk-through joint
+ non walk-through non articulated joint
= car

4 car

6 car

The pic below shows what they look like

that looks simalar to a millennium class.

I believe you are referring to the Sydney CityRail trains? Not bad, but they were late and not very good. Built by Goninan. Excellent for the City Circle tunnels.
