A question about rails and rail stations

[CommanderABab]

How do the inhabitants and workers decide to walk to the train station and use the rail system?

Do they use the road and or bus system to reach the rail station?

[Lobby]

Randomly, if a train station is nearby.

No, logic here is really simple and yet expensive in calculations.

[CommanderABab]

So t will take about half the traffic from a building off the road?

[Lobby]

Theoretically, you may reduce traffic by 80%, but 50% is way more realistic.

[Lobby]

Actually, people should favor train over bus.

Tickets shouldn't exist anymore, we used them in the past to track how people move through your city.
