In recent years, the speed of trains has been greatly increased. When train No. 1427 travels from station A to station B, when it travels to 1/3 of the whole journey and then moves forward 56 kilometers, the time it takes is 60 minutes shorter than before, and it arrives at station B earlier. In 2 hours, find the distance between the two stations AB.
