Maybe I'm a bit of an outlier here but why do some people on trains feel they need to be connected to the internet every second of their journey? If you want to entertain yourself over the course of your journey, try looking out of the window; the view will be far more interesting than anything you can see on a mobile or laptop screen. If it's dark or you're travelling through a dull industrial area read a book or maybe listen to some music on your mp3 player. None of these activities require a wifi connection.
I do a journey which is two hours each way 2 or 3 times a week. That can be used as working time to get technical tasks done, making progress on projects or sorting out business related matters.
Looking out the window at the same scenery for 12 hours a week isn’t a terribly productive use of my time. If it wasn’t possible to work on the go then I wouldn’t be doing that journey at all, I would have to reside much closer to work.
But, if you travel for leisure, or travel time is a chance to get some peace from home and work then using that time to relax is a more attractive prospect and internet might not be that important.
There are different types of passengers using the trains and connectivity will be a trip generator for some people.
