Trains are considered one of the safest modes of transport, so the railway will be relevant for a long time, and in Train Racing 3d -Play you can try out new routes to make sure they are completely safe. At each level, you need to run trains one after another so that they pass the route allotted to them without colliding with another train. First, start the blue one, and then after a while the second one, and then the rest, if any. At the intersection of the tracks, the trains must pass freely without meeting each other, which means that the interval of movement is necessary, which you will have to determine in Train Racing 3d -Play.
