Who decides what temperature trains should be heated to? On the old rolling stock it is possible to open the window when a carriage is inappropriately heated, not so the new rolling stock. A central heating survey suggests that on average we heat our home to between 20-21C, so why do trains need to be hotter? Many passengers are wearing outdoor clothing so surely heating the trains to 23-24C is simply wrong as well as wasteful.
Hi Stephen, this is a really thorny issue with lots of customers, all trains should be set to 20 degrees in the winter and this allows for the doors to be opened numerous times letting out lots of warm air. As you can imagine if it the carriage is heated to 20 degrees and then suddenly becomes full the air con can sometimes kick in and customers complain that we are pumping cold air in. it is impossible for us judge how busy the train is going to be all day and then run round adjusting them every night depending on the weather. So we try our best but most of the time we can't please everyone.
On your busiest commuter services I've seen many passengers looking seriously uncomfortable on you newest trains, and some even looking distressed. Bearing in mind the risk of a cardiovascular attack escalates meaningfully and rapidly from 24C it seems odd to me that you think 24C is an appropriate target. Can I suggest you re-introduce opening windows so that your customers get an option when you get it wrong?
More basically, are the thermostat sensors near doors which open at each stop?
If they are located near doors, they will detect a rush of cold air at every stop and try to counteract that.... It is what the system is programmed to do! I seem to remember stories of both French and German railway companies having similar problems. At home your central heating thermostats are located well away from doors for that reason.
Be thankful that there is heating. Have a look at the equivalent forum for some other operators outside the South East. ( Giving their names would probably get me banned, even though they are not First Group.)
I don't know how you can use this as an excuse. If you go on the Circle/District/Metropolitan lines they handle this fine. This is not rocket science. Also your comment we can't please everyone - you aren't pleasing anyone at the moment!
Agree with all your comments apart from the last one. We are all wearing winter clothes and so should be fine even without heating. Issue is when there is heating everyone is wearing jackets and coats and it's 25deg on the train which is much worse. Whoever decided this really needs to have a rethink of what customers really want. Spending this much money on trains just to make the journey less comfortable than the old trains with windows, what's the point??
