18TN

General Information

Here are some highlights of rules in 18TN:

The Illinois Central presidency is a 30% certificate. (§3.2-5)
When the 2nd 6 train is bought, all 4 trains become obsolete - phased out. (§4.2.5.1)
Corporations purchase of companies from players (§4.2.6):
- During OR1 - This purchase is for face value only.
- During phase 3 and 4 - This purchase is for 50%-150% of face value.
- At all other times purchase is not allowed.
When the 5th 3 train is bought all corporations with trains will get a Civil War token (which appear as an ability on the corporation charter). The next time a corporation with a Civil War token runs trains, the train that gives least revenue is changed to give revenue 0 for that run. After applying that effect the token is removed. (§5.1)

The map differ a bit in Memphis, Chattanooga and Nashville compared to the physical game. This is for implementation reasons to make the upgrades work smoothly:
- Memphis hex works as a normal city hex, but when upgraded from green to brown it is allowed to upgrade to either a normal tile (63) or a P tile (170).
- Chattanooga hex uses a C label for yellow, and has a green tile with a C. When upgraded to green the label is changed to P as only the P tile is allowed for brown upgrade.
- Nashville hex uses a N label for yellow, and has a green tile with a N. When upgraded to green the label is changed to P as only the P tile is allowed for brown upgrade.
The 3' train is for all purposes a 3 train. It is just to make it possible to have a phase 3½
The 6' train is for all purposes a 6 train. It is just to make it possible to have a phase 6½
