Brilliant, thank you very much for the swift answer! That was bugging me for a while so it’s good to finally know what it’s used for. Thank you very muchIt's a porter switch, so you can close and lock doors one carriage at a time. Particularly good at closing doors at terminus stations.

They used to be just buttons as on some other types of stock. I guess having a T key needed stops any passengers from having a 'I wonder what happens if I press that button?" moment.
They are particularly useful, so it surprises me they're just a South East thing.
Outside of the South East there’s a guard on board to do detraining.
Inside the South East there often is as well. LNR have porter buttons and guards.
As the 350s are a derivative of the DOO-designed 360s that came before them I suspect it was more hassle to remove them from the design than maintain them.

The 450s are not the 360s that JN114 was talking about.Surely it's the other way round as I believe the SWT 450's came first and the original 350's were part of that order (they were going to be 450's but the government stuck their oar in).
Yes, the provision of porter buttons and guards is not a mutually exclusive thing; however DOO stock is required to have them fitted.
They are well used, however.
Class 700s don't have them.Do you have a source for that please ?
Cheers in advance.

External buttons are hopefully a thing of the past on new stock.
I should have said for open gangway stock, which a lot of new trains are likely to be (not Intercity type trains obviously). Far easier to walk through inside than getting out and walking to a button, then back on the next etc.
