What is the region limit for two players?
Quick answer
In a 2-player game, each Region has a limit of 3 Train spaces, while each Local Market has 2 available Influence spaces, and each Destination allows 2 Ships.
Details
The Trains action states there is a limit of Train spaces per Region: 3/5/7 for a 2/3/4-player game, respectively [p.13 — TRAINS ACTION]. So in a 2-player game, only 3 Trains can be built in any single Region.
Similarly, the Local Markets action has a limit of available Influence spaces in each Local Market: 2/3/4 spaces for a 2/3/4-player game, respectively — meaning only 2 Influence spaces are normally available per Local Market in a 2-player game [p.14 — LOCAL MARKETS ACTION]. However, in a 2-player game, you may place a token on the 3rd empty space in the Local Market if it has a higher value than at least one existing token, which then bumps out the lowest-value token [p.14 — LOCAL MARKETS ACTION].
The Ships action also has a per-Destination limit: 2/3/4 Ship spaces for a 2/3/4-player game, so in a 2-player game only 2 Ships can be sent to the same Destination [p.12 — SHIPS ACTION].
Watch out: These limits differ depending on which component you mean (Trains, Ships, or Influence tokens) — make sure to specify which type of "region limit" you're asking about, as each has its own separate cap [p.13 — TRAINS ACTION][p.14 — LOCAL MARKETS ACTION][p.12 — SHIPS ACTION].
