    I notice some trains have enhanced mobile phone coverage and wi-fi. I
    wonder how that works. Does the train have to be within reception for
    mobile coverage and within a 3G (or 4G) area for wi-fi to work, or is
    there a different way of getting the signal to the train?

    Is there perhaps a 25kV version of the powerline adapter to allow
    distrbution using the overhead line equipment?
