Just noticed on RTT for London Bridge there's a lot of "Q" (runs as required) entries from Brighton/ 3 Bridges to Bedford. Not just that, but they're all only Northbound, no Southbound thru that way as far as I can see.

Another "benefit" of the open plan straight through access design of these units is the chance to sit in a wind tunnel while they load up at a terminus as a cold wind blows through the length of the train. Must be pretty wasteful on energy too...

I thought the same at London core stations where every door platform side is automatically opened.

Obviously designed to minimise delays with embarkation/disembarkation, it results in a warm interior changing to an icebox within minutes. Surely the automated opening of all doors is only needed during peak rush-hour periods and could be limited to those periods.
Off-peak should be left in the hands of the few passengers who are leaving or boarding the train.

It'll probably take as long as it took them to sort out the random 'one' announcements on the 387s :lol:

Are they on all core stations? Is it just the two wheelchair doors that are level, I have seen a photo of the on at St Pancras but the train was moving so couldn’t work out from the photo.

I saw a conversation on Twitter earlier about 700s roasting passengers and a claim that the heating is making the trains vary from 25 to 30 degrees inside. There was an accusation that nearly all the trains are like this and TL refuse to deal with the problem.

I have to say I've not experienced this, although I was on a 387 on GN earlier this week that was like an oven.

Is it a big problem now we've had some very cold weather, or a massive exaggeration (not least that I am not sure anyone will have actually measured the temperature)?

Some 700s I've been on have been fairly warm, but not really any different to any other stock that I've noticed. They seem perfectly reasonable to me.

What about when they are fully loaded? Can the air con cope?

The 700 this morning had awful condensation on the windows. I might expect that on a Pacer or 423 but not on a train built in the 21st century.

I assume a problem with the air conditioning, failing to remove moisture properly.

Aren't the 700s supposed to increase the power of the AC based on how many people are on the train?

I know there is still a setting for the temperature though and I did hear that some have it set higher than others.

I find the 387s fairly airless, and I’m clearly not the only one as it’s very common to see people trying to open the windows on them. Perhaps someone could make a bit on the side by making and selling the relevant bits of a T key to commuters?

GN commuters seem to have a lot more of a problem with 387s than their counterparts who travel on Gatwick Express, experiencing near enough identical trains, just with a different paint job! And when it comes to the Southern and GX Electrostar fleet, those trains typically attract far fewer air con complaints than anything running north of the Thames. I really don't know why this should be.

GTR has actually spent a copious amount of money and time in air con overhauls for older trains, and the HVAC systems on 700s and other newer stock do seem to be getting better. I spent several exceedingly uncomfortable journeys on freezing 700s last winter, but I'm yet to have a problem a year later. The same applied with air con seeming to get better towards the later part of summer. As for 387s, I must admit I've never really found any with major problems.

One thing is certain, though - trying to open the windows in the event that the HVAC has not failed is likely to make the problem much, much worse. Those windows do very little and are chiefly for emergency ventilation and to mitigate against total air con failure in the summer - but opening them for "a bit of air" in the middle of winter is likely to direct a freezing cold jet of air at the air handling systems, which will not do them any good at all.
