The actual length of the block sections, determined by the inter-train interval, is considerably greater than the estimated length required for traffic safety. The similar arrangement of traffic lights leads to an underestimation of the available throughput. To bring the lengths of the block sections into line with the braking distance, it is suggested to consider the movement of trains at the yellow indication of the traffic light without reducing the speed. Reducing the braking distance, the length of the block sections and their number will increase the carrying capacity, especially in the areas of freight traffic. Satellite radionavigation systems that regulate traffic without floor traffic lights and rail chains can help to ensure the minimum required interval between trains. Keywords: railway, throughput, length of the block-section, braking distance of the train, inter-train interval, arrangement of passing traffic lights, satellite navigation.
