+50% International Train passenger and mail capacity
Terminal is a Special Building that adds a bonus of +50% to the number of passengers and mail carried by Passenger Wagons, Mail Wagons, and Passenger & Mail Wagons pulled by International Trains when leaving a player's station. The bonus also applies to Special Wagons, also called "XP Wagons", that are attached to these trains. Special Wagons attached to cargo trains receive this bonus from Container Storage instead of Terminal.
