I don't know if this is the right thread but it is a kind of refurbishment of sorts.
I noticed a 455 had WiFi today. Later on I travelled on another service and that had WiFi too. Whilst it could be the same rolling stock it probably isn't.
They say half their trains have WiFi and look for signs on board but I can't see any signs.
The WiFi name is: SWR-FREE-WIFI. As it's not the same name as other SWR trains WiFi, I didn't notice it was avilable. Not sure how long is been going.
If your on a 455 or even 456, check out your WiFi as you might be pleasantly surprised.
I prefer the layout of the sign on to this WiFi compared to the 450/444. Every clickable option is viable by default.
This is a wonderful improvement and before I read they were going to do this, which I think was some months ago, unexpected improvement.
