The task is to regulate traffic on a railway crossing. The train will be able to cross the railway only when the gate is open. It is possible to close the gate, but this will not prevent accidents. It is necessary to pay attention to the traffic, especially to the speed of the trains.

The task is to keep the gate open for as long as possible to allow the cars to pass through without getting hit by the incoming trains. You need to control the gates on either side of the track, according to the direction of the train. This can be done by pressing the appropriate button.

It is possible to get to the next level by allowing a fixed number of cars to pass through the crossing without any accidents. The difficulty of the level increases with each step.

Each level contains a time limit.
