Or trivial information perhaps.
So, having been out of the country for some time I’m getting on a London to Bath train. As I’m pottering along the platform I spot the train manager (conductor to us old folks). And I ask, him, sorry, been away a long time, do trains have wifi these days?
Yes, most but not all. Fire up the box and see.
Ah, and here’s the trick. As a carriage is taken out of service to be sorted out for maintenance, then they install the wifi kit.
And most carriages now have it. But not all. However, any carriage that is behind one that doesn’t have it won’t have it either, whatever is in that specific carriage.
And it always starts from carriage A. So, if A,B and C have it, but D does not, and E,F,G have it, then E,F,G won’t work because D doesn’t.
OK. So, always sit in A or B to have the best change?
Yep, except if you’ve a first class ticket of course. That’s G,H and so on.
What? So first class has the least chance of having wifi?
Yes. Lovely piece of planning that, isn’t it?
