In Shopping Tycoon you can expand the transport so that more people come to your mall center.

You have a subway station under your mall center parking. The subway is inspired by the city of New York and you have many lines that you can unlock as you progress in the game.

The subway lines are inspired by cities around the world. A display will show you the arrival time of next subway.

Passengers will pay the amount of the subway ticket, so your income will grow when you have more unlocked subway lines and more passengers come to your mall center.
