The pods are roof mounted on the carriage and have lots of different sim cards in the pods attached to different networks, the system pipes out the strongest network, but if they're all showing as no service no Wifi will be provided.
Thanks for that explanation. I didn't know that. Now fascinating. Well there are clearly parts of the South Western Railway network where no mobile phone provider is any good.
Incidentally once 15 minute relay repay goes live, I can see the situation where SWR are constantly having to pay out compensation at Wimbledon for people missing the Sutton loop services. The official connection time is 6 minutes.
I was only 3 minutes late into Wimbledon. Alas it takes so long to leave the platform that you miss the train. I had 2-3 remaining. The footbridge wasn't even that busy. It's just the lack of stairs up and down that's the issue. I was stood at the wrong end of the platform, which was my fault, so I was towards the back of this queue. However unless I was at the very front of the queue, not sure I'd have made it. Of course delay repay doesn't state where you need to stand or sit on the train in order to claim.
Perhaps SWR could just make the official connection time at Wimbledon 10 minutes. Then they wouldn't need to pay out as much compensation.
SWR did say in their recent advert that Wimbledon station would see improvements. I hope this includes an additional footbridge at the be other end of the station. I am aware I was planned and cancelled but maybe it can be reintroduced as an idea.
After all they added platform 7 at Gatwick Airport and extended the footbridge to it. They even made a waiting room and changes to entrance to platforms 5 and 6, the ones most used by Gatwick Express services. All this despite the fact that the they are planning to remodel the station anyway in the coming years.
Could they just not put up a temporary bridge at Wimbledon for the intervening period?
