Coupons are a new kind of train card. There are 6 kinds:
- Austrain Railways
- Transylvanian Transport
- GHR
- Southern Railway
- Bohemian Rail Network
- Galician Rail Lines
They can be used to claim certain routes as a substitute for train cards. For example, to claim Wien-Budapest, I could use 1 green, a locomtive, and an Austrian Railways coupon.
Coupons only appear in Austria-Hungary.
