The Underground Subway Station is an infrastructure building that can be purchased from the Buildings tab of the Subway Administration Building. It was added during an update on 12.20.2013.[1] Up to 5 Underground Subway Stations can be built, with each increasing the cost and reward of Subway Train contracts.

A total of 50 assets are needed to complete construction of all 5 Underground Subway Stations. This equates to 50 Megabucks sm if one were to buy every asset instead of waiting to receive them from neighbors.
