I’m currently on a high speed train between France and Switzerland and wondering how my cell phone is able to keep up with my very rapidly changing position and generally keep data connectivity?

As fast as you’re moving, you aren’t moving at light speed. The signal between your phone and the tower, however, is, and as long as the network hand-off protocol is working properly your speed relative to the tower(s) doesn’t really matter. It *really* doesn’t matter unless you’re in an active call at the time, anyway.
Of course, that’s assuming there isn’t any cellular infrastructure built into the train system, itself, which isn’t at all uncommon these days. You’ll find cellular relays built into trains, subways, large population venues, etc. all over the world.
