In railway signalling, a moving block is a signalling block system where the blocks are defined in real time by computers as safe zones around each train. This requires both knowledge of the exact location and speed of all trains at any given time, and continual communication between the central signalling system and the train's cab signalling system. Moving block allows trains to run closer together (reduced headway) while maintaining required safety margins, thereby increasing the line's overall capacity. It may be contrasted with fixed block signalling systems.

| - In railway signalling, a moving block is a signalling block system where the blocks are defined in real time by computers as safe zones around each train. This requires both knowledge of the exact location and speed of all trains at any given time, and continual communication between the central signalling system and the train's cab signalling system. Moving block allows trains to run closer together (reduced headway) while maintaining required safety margins, thereby increasing the line's overall capacity. It may be contrasted with fixed block signalling systems. Communications Based Train Control (CBTC) or Transmission Based Signalling (TBS) is required to detect the exact location of trains and to transmit back the permitted operating speed to enable this flexibility. Information about train location can be gathered through active and passive markers along the tracks, and train-borne tachometers and speedometers. Satellite-based systems are not used because they do not work in tunnels. Another version of the moving block system would be the location computers on the trains itself. Each train determines its location in relation to all the other trains and sets its safe speeds using this data. Less wayside equipment is required compared to the off-train system but the number of transmissions is much greater. (en)

Agar sistem ini dapat bekerja, dibutuhkan Sistem Kendali Kereta Berbasis Komunikasi (CBTC) atau Transmission Based Signaling (TBS) untuk mendapatkan informasi yang akurat mengenai keberadaan kereta pada waktu tertentu. Sistem kemudian memroses data yang didapat, kemudian mentransmisikan kembali informasi ke kereta yang bersangkutan dalam bentuk kecepatan operasi yang diizinkan. Informasi tentang lokasi kereta dapat dikumpulkan melalui detektor aktif dan pasif yang dipasang di sepanjang lintasan, beserta takometer dan speedometer yang dimiliki oleh kereta. Sistem GPS berbasis satelit tidak digunakan karena tidak dapat bekerja ketika kereta berada di dalam terowongan. (in)
