GLASS OVER THE M DOORS

I'm sure the 1972 stock has it too......

There are many reasons why access to train cabs needs to be controlled. I belive C stock had a spell where cabs were being vandalised.

I'm sure the admins will agree that postings of what switches/buttons/controls would have what, if any, effect on the train is not appropriate for this site.

Mmm, indeed. Will something similar appear on the 73 and 92ts I wonder.

It's glass for a reason - it provides enough of a barrier to prevent most people bothering to even try and access the cab yet it can easily be broken if required for emergency access. It's just the same as the J door installation on all LU stock (the J door being the cab access from the passenger saloon).

C stock is made up of 2 car units, so there will always be a cab in the middle - of course the Bakerloo's 72ts and the Met's A stocks are also similar in that they always have cabs in the middle, though I wouldn't profess to know if they have similar installations. In fact I wouldn't have thought the A stock would as they always have two middle cabs (Chesham shuttle excepted) and one would have to get past either J door first, which of course will have a glass cover anyway as it's a common standard on LU.

Absolutely Aspect - drivers will know what's what with their particular stocks but we don't want anyone 'unsavory' knowing anything.

I expect that's quite possible with A stocks, but on all other stocks (AFAIK) that would cause problems with the door interlocks.

The Picc's 73ts, like the District's D stock, only has a limited number of 'double ended' units where a cab would end up in the middle. I would therefore suspect it's not really worth the bother of making such a modification.

As for the Central's 92ts, it's extremely rare to get a cab in the middle and so it really would be a pointless exercise modifying them.

Since starting a 'new' job at Paddington I've been using the Bakerloo and normally sitting in the carriage adjoining the middle cab and I can confirm they do have the glass cover over the handle. In most scenarios where a glass cover is over something there are also normally signs advising you not to break it with your bare hand - hammers often being provided but no warnings or hammers on LUL.

I would guess the 1967 stock don't have glass over the M door handles either. At least you can't leave their side cab doors open!

Aren't D Stock still supposed to be getting the 'M' and 'J' door intruder alarms fitted, along with the long promised 'J' door bottom strip?

The 67 stock don't need it as the middle cab always faces a middle cab. You can't get a middle cab facing an communicating door.

As for the D stock, I've had two trains now that have the J door bottom strip fitted, but none of the other stuff.

Perhaps a way around this would be to fit a carriage key type lock on the outer door which isn't spring-loaded (thus doesn't lock automatically), but when stabling at an unsavoury set of sidings, could be locked? Obviously when the next driver comes along he'd have his key with him to unlock it.

Drivers often leave their offside cab doors open during hot weather, it is allowed and on stocks without cab air con like C stock it's the only real way to get some ventilation.

You wont see a middle cab door open on a C Stock train in service because all non operative cab doors become part of the train door interlocks and will prevent a pilot light being obtained when open.
