New Hampshire
Right next door to Vermont, the New Hampshire Steam and Age of Steam expansion features strict anti-competitive measures that ensure there's no collusion amongst players. This map contains the following special features:
Unique Track Builds: Track builds can not be duplicated; once a player has built a section of track between two locations, no one else can build that same connection.
No Track Sharing: Players must deliver goods across their own track only.
Players: 3-6
Optimal number of players: 5

The biggest expansion ever created for Steam and Age of Steam, Central New England plays up to eight players simultaneously and uses all the rules from Vermont and New Hampshire in addition to a few new rules specifically for this combination map:

Smuggle: This action allows players to secretly deliver within the same state.
Support for 7 & 8 players : Up to eight players may play at the same time (requires additional track/scoring markers, not included).
