Age of Steam Expansion: Double Base USA / Pacific Electric

From BoardGameGeek:

The Age of Steam Con 2021 Map Set contains two new maps. Double Base USA This map is the first to use two copies of Age of Steam. The map is a two-piece poster that is assembled to create a gigantic map. Players start their networks from the east coast and expand westward. Government land grants in the West help players build more track and get more deliveries. Track build limits double in later turns. Players can get up to a 12 Locomotive. Pacific Electric Players build a network out of Los Angeles into the surrounding cities using Power Plants to increase the length of deliveries on their electric rail network. This map shares a common core with Age of Steam: Kansas City Interurban and adds its own unique twists and geography. The Express action allows players to deliver through a City matching the good color. The Engineer action allows players to build on rough terrain hexes. The map size is small and promotes a lot of player interaction.
