Could more reliable, universal train wifi be provided?

I really have no idea what I'm talking about here, but bear with. I recall that Teletext was provided by "piggybacking" on to redundant capacity in a standard TV signal. Are there rail systems (track circuits? signalling cables? electrification infrastructure? etc) that could, if the will was there, be used to provide a carrier signal for reasonably reliable, fast wi-fi? If so, could this provide a real competetive edge against the airlines?

Simple answer, no.

When the train WiFi signal (to the Internet) is poor/unavailable, the main reason is there is no mobile reception at all.
So reversely, when the train WiFi is good, there should be no excuse mobile signal being bad (though it could be due to train chassis shielding that blocks mobile signal)

The easy solution to improve signal in a whole is to build mobile base stations all along the railway. Easy, just money.

When the train becomes fast and affordable and comfortable and reliable you will find the passengers from the airlines return to it in their numbers. Once you've done that then perhaps some low-cost 4G or 5G boosters on board trains to enhance existing signal on customers devices but if you absolutely have to spend money on Wi-Fi then NH I'm sure that easyJet and British airways and Ryanair passengers would like some even if it's just slow and and we certainly like some decent premium Wi-Fi at airports but doesn't cost the earth and allows us to make use of the time whilst there

Personally I think investment in this area is a total waste of resources. Signal provision is only ever going to get better and better and better mobile data packages are becoming available, such as all-inclusive data, which are rendering Wi-Fi provision increasingly irrelevant.
