Travelling through Stations.

The time is surely enough. You do not need to exit from the station, you can use the transfer passage. In this way, you do not need to go through security check again. There is a a few signs of "transfer" can be find. After your arrival, you can upstair to the waiting room, then you can wait for G655 in the waiting area. It is very important that you must hold the paper ticket in hand for the next ride on G655, otherwise, you cannot make this transfer. And do not go downstairs to the station exits!
