Priorities
Well that sounds like it will make fares cheaper so a +1 from me. Waiddaminute!
Since public transport is clearly aimed at the luxury travel market these days, I would expect very decent connection speeds.
When East Coast GNER National Express (or whatever they're called this week) say on-board wifi what they mean is a bunch of 3G/4G dongles bonded together across the length of the train. Not that it matters. I'd rather use my own bandwidth from my phone/whatever device, than a connection shared amongst a carriage or 12.
