London Subway Simulator (or, to use its full name, Subway Simulator 2 - London Edition) is an app designed to make you feel as though you are driving a train on the London Underground. Navigate your train from station to station, picking up passengers and depositing them at their chosen locations. The app offers multiple different viewpoints. You can watch the action from the cockpit of the train, or from a first-person perspective in front of the train, or even from the viewpoint of a passenger in one of the carriages.
