Steam: Map Expansion #4

Steam: Map Expansion #4 transports the railway adventure to two brand‑new regions. In South Africa, 3‑6 players must juggle mining resources with local market trade, adding a fresh economic twist to the base game. The Polish side introduces "Broad to Standard Gage Transitions", letting games of 2‑4 players adjust track gauges to fit the scenario. The expansion provides two rule sets: one streamlined for 3‑4 players and a tighter version for head‑to‑head 2‑player duels. Beyond the new geographic boards, it adds a fresh tile sheet compatible with Steam's standard boards and extra transition tiles that complement Map Expansion #3. Core Steam mechanics—auction, network building, pick‑up‑and‑deliver, and tile placement—remain, but gain new depth thanks to the South African and Polish routes. Playtime ranges from 60 to 120 minutes, depending on player count and rule familiarity. With a 4/5 weight, the expansion offers solid strategic depth without overwhelming complexity, perfect for fans of the original looking to expand their rail empire.
