| Traditional signalling systems are based on fixed blocks. In a moving block system trains are continuously controlled and kept at braking distance from each other. This is realized by a Radio link to the control centre. Moving block systems increase line capacity and improve traffic fluidity and thus energy efficiency. Moving block is foreseen by ETCS level 3.

Railway signalling has traditionally required a large amount of expensive hardware to be distributed all along a route which is exposed to variable climatic conditions, wear, vandalism, theft and heavy usage. Because of the widely spaced distribution, maintenance is expensive and often restricted to times when trains are not running. Failures in wayside equipment are difficult to locate and difficult to reach. On metros, access is further restricted within tunnels and elevated sections. Moving block requires less wayside equipment than fixed block systems. Estimations made in the context of radio controlled regional lines indicate considerable cost reductions for personnel and maintenance due to a strong reduction in way-side equipment. |
