First time I used one of the 319s on Thameslink with PRM-TSI modifications installed. Disabled loo looks the part, the door sounders are annoying as expected but do the job, but the PIS... ugh. I don't understand how you can get that so wrong after all this time! I am going to be polite and assume the fact all it says is 'welcome to this Thameslink service' because they haven't programmed them up yet, but the bezel covers up the top pixel most of the way across, so the dots of the letter i are invisible apart from at the outer edges, and it's sufficiently bright that it's a bit difficult to read (a problem I've found with the 387 PIS too tbf, but at least that is otherwise functional). I'm surprised after all this time PIS systems are still so inconsistent and low-quality, but there you go
