Does all current LU stock have cab air conditioning? I know that the 2009 and S stock had it from new, but have older stocks been retrofitted?

The Waterloo and City Line doesn't have air con, the unions keep asking for it but at the moment we have to drive with the cab door open if we want a bit of a breeze.

The Class 482s on the Waterloo & City are identical to the Central Line 92ts except they don't have air conditioning and ATP/ATO but they do have tripcocks.

Presumably the usual problems with aircon on a train which spends all its time underground - where does the heat go? The Central Line is a different kettle of fish - they spend more time on the surface than under it.

Was the 92 stock on the W&C built with cab air conditioning which fell into disuse, or did it never have it? Come to think of it I’m making an assumption that the 92 stock on the Central had it from new. Is this correct? |

The air con in the cab doesn't generate a lot of heat, air con for a whole train is a different matter |

If the 92ts on the Central Line didn't have air con from the start it would have been horrendous as ATO won't work with the doors open. They certainly had it since I started working there in 2003 I don't think the W&C ever had air con, there's no grating in the ceiling for it and it certainly wouldn't fall into disuse, more likely get worn out through overuse! |

Thanks for that reply. It seems strange for it to be actively dropped from the W&C specification given the units were otherwise pretty much identical - originally! The 73 and 83 stocks must have been pretty unpleasant in tunnels with sealed cab doors. IIRC the 73 stock only got cab air conditioning on refurbishment. |

The 1992 stock definitely didn’t have air con when they were introduced, although in the days before ATO they sometimes used to run with the far side door open in the tunnel sections
I imagine that the 1967 stock was worse, because ATO would not work unless the cab windows were closed.

The 1973 stock had it retrofitted in the 1990's refurb. Prior to that, it had ambient air blowing through a vent.
In the winter you could turn on the heaters and hot air would blow through it.
Drivers used to plug it with newspaper to make it blow hotter.

Cab windows on 1967 Stock could be lowered a few inches in ATO mode, a red line indicated the extent of travel. 1972 Stock and C Stock were fitted after refurbishment with primitive Peltier coolers rather than full A/C. |

Just looking through a handbook for 92 stock dating from the 1990s. Can’t find any mention of cab air conditioning at all - the only reference is to pressure ventilation. I find this surprising, however from this unless anyone knows different it appears the 92 stock cab a/c was a retrofit - which would explain why the W&C units don’t have it. |

I don’t even think the 95 and 96 stock had air con on delivery.

They were being designed around the same time as the 73 stock refurb, of which improving the cab was a major part of the specification. Wish having a better secondman’s seat had been thought of then too, as that is one feature of the older stocks which is ripe for improvement. |
