Hint: if your reply explaining to me how simple and affordable the train ticket system in your country is is so long you put it behind a CW for length. It's not a simple and affordable ticket system.
For comparison. The Dutch system.
"About €1.5 to check in, then about €0.15 per km. An extra ~€2.5 to use the high speed. You can get discount cards for off peak"
There you go, under 140 characters.
That's how simple a fare structure should be.
