Have you ever had a difficulty in finding out how much the train fare is?
If so or if you are in a hurry, why don't you buying the cheapest ticket first?
Next, you need to find the machine as below just before getting out of a ticket gate.
The picture abouve is from http://trns.homeip.net/SubEquipment/Sect1.html.
Don't worry, it (fare adjustment machine) is located near ticket gates and you can find it easily.
