Age of Steam: (KS) Scotland - 2p Teaching & Play-through by Heavy Cardboard

About Age of Steam Expansion: Scotland, from BoardGameGeek:

Age of Steam: Scotland is a map specifically designed for two players. The game was designed by Kevin Duffy but not specifically published and was print & play. When Steam was published, this expansion was adapted for the new game. Phalanx Games Polska ordered a redesign of the map. New graphics were prepared by Piotro from Board of the Loom. In 2023, this map was included as part of Age of Steam Deluxe: Expansion Volume II published by Eagle-Gryphon Games.
