But since the train is moving pretty fast, a special wifi router is used to talk with these wifi access point and then broadcast back into the train. something like this pepwave mobility while it cost a lot to setup these internet backbone, but there are no monthly usage charge like the satellite or edge based method. there are many ways to provide wifi on train.

When you say it looses the signal leads me to believe they are getting and loosing there signal via Microwave Tower, or Satalite dish on the train.
