Stoplights is all about management, planning and efficiency. Your goal is to establish cities near resources, connect them together with rails and manage automatic train routes by placing traffic lights.
The needs of a city grow with time, so expect your rail network to be stress tested in an increasingly complex network of intermingling trains.
Inefficient routes, misplaced signals or lots of time spent waiting at a junction will be the difference between success and failure.
CORE MECHANICS
Build cities, rails, and train signals
Manage traffic by dividing long rails into shorter segments via signals
Indirectly control automatic train routes, which seek out nearest available and unobstructed resources in connected cities
