Great Western Trail

You must move at least 1 step and may move up to the step limit shown on your player board (start is 3 or 4 depending on player count); you must move forward along the trail (no backwards movement) and cannot pass over Kansas City (p.6).

You must immediately pay the indicated fees (to the bank for hazards, to the owner for private buildings) as you pass or land on them, but if you cannot pay you are still allowed to move — pay as much as you can and you never owe fees retroactively (p.6).

On a neutral building tile or a private tile you own you may perform each of that tile's local actions once (in any order); you may only perform an auxiliary action instead if you forfeit all of the tile's local actions (p.7; local actions explained pp.11–14).

Your Income subphase sets a total breeding value (sum of different cattle types plus certificates) and you may deliver to any city whose city value is ≤ that total (you cannot deliver to a city you already have a disc on, except Kansas City and San Francisco); transport costs apply if your engine's nose is behind the city — pay $1 per crest between your engine nose and that city's crest — and disc placement follows the white/dark corner rules (pp.8–9).

Each auxiliary action has two disc spaces: if at least one space is cleared the action is unlocked (single use), and if both spaces are cleared you may use it as a double action (requirements and rewards doubled); note that using an auxiliary action from a location in place of local actions can only be a single use even if both spaces are cleared (p.13).

The game end is triggered when a worker is placed on the last job‑market space during Kansas City subphase 2 or 3 (moving the job market token out); the active player finishes that turn and then each other player gets one final turn (they may go to Kansas City but cannot take worker tiles from foresight during their final Kansas City subphases) before final scoring (p.15).
