Heating in summer?

This is a perrenial problem not limited to the Metropolitan line - I've experienced it on most trains, tubes and busses.

For as long as I can remember, I've been utterly baffled by the practise of having the heating ON in summer and OFF in winter.

Roll on trains that do the switching for you - but I would bet that even then it will always be too cold or too hot for some people.

Generally at this time of year, the heaters are meant to be off. But sometimes those very early morning services can still benefit from the chill being taken off. Sometimes as the sun gets higher, the fact that they are on is overlooked by the train operators - the saloon heating is not linked to the cab heating.

EDIT: t697 beat me to it whilst I moved from the computer mid-typing. I don't know the official reason why the fuse removal ceased, but can bet it's linked somewhere to the extra work hours to remove then replace them.

I quite like having the heating on and off at the turn of a switch - and the open windows!

I'm sure a quick word in the t/ops ear would ensure the 'H' was turned off. It's a bit like the destination blind not being reset. Met drivers are a friendly lot, they don't bite! ;D

Well, yes, I couldn't have done it mid-journey, but happy to report that there was no heating this morning!

I had a bus a few weeks back which was baking hot, but controls were accessible only by an engineer when the bus was on a pit. After numerous passenger complaints I booked the bus defect card, however as the evening wore on the bus became freezing cold and i deleted the defect report. It's an absurd design on such buses but we are stuck with it. Also a few buses are prone to overheating and keeping the heaters on (which take heat via water from the engine) keeps the bus serviceable longer. A quick fix until the problem can be sorted (if they can, in fact, find the source of the problem).

On trains the thermostats are apparently prone to jamming in keeping the heaters on. Rather than replace the thermostat, the fuse would be pulled, leaving the train freezing cold early morn and during the evening. D stock were very prone to this. One year they pulled the fuses on the whole fleet (totally unacceptable early or late) and when it came time to put them back one depot had lost all theirs (belived thrown away) and they were scratching round other depots such as Northumberland Park for suitable fuses. none the less some cars remained heaterless all winter.

I am told the thermostat was replaced upon refurb (and relocated into the roof void, from by a window (don't forget the window didn't exist as D stock was designed)) but now the temperature setting on it can't be altered, only the unit replaced. They are supposed to be set the same, but clearly are not, it remains notable thet some cars are very much colder (or hotter) than others.
