Only 62,7% of the trains were in time (and by in time they use a rigged system to count what is in time and what is not). So it's basically a 50% chance if you will be delayed at your destination or in time. Also note, that if you have to change trains mid travel you have that chance again. That means you will be late very very often. If you travel as an individual and you don't value your time at all this is a great deal, if you travel for business purposes good luck to you.

Apart from that, it's a lot more stressful (and time consuming) to go to a train station and leave at a train station instead of just driving by car.
