    Quick question:

    I'm on the train at the moment.
    If the train had Wifi, would the signal from the source be travelling at the same speed as the train?

    Also would a house computer by the railway be able to pick up the signal for a brief moment as the train passes?

    Wifi moves at the speed of light (not the vacumm one of course)

    I'm not a scientist, but the signal would be at the same speed as the train.

    >Also would a house computer by the railway be able to pick up the signal for a brief moment as the train passes?

    No, unless the Catenary poles are installed with wifi transmitters.

    The signal would be traveling at the speed of light, but as distance increaces, the signal gets so diffuse it becomes unusable. Any doppler effect at these speeds are negligable.

    >would a house computer by the railway be able to pick up the signal for a brief moment as the train passes?
    Maybe, it would depend on refresh rate. Also, lots of things can extend the usable range of wifi.
