| 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.

Train control systems based on moving block show a better traffic fluidity than today's fixed block systems do. This will increase line capacity and have a positive impact on energy efficiency of train operation. The most realistic lane towards moving block in European railways is presented by level 3 of ETCS. However, co-ordination efforts, interoperability issues and high investment costs of the required system transition are expected to delay introduction of the higher levels of ETCS. More reliable information of the energy saving potential of moving vs. fixed block train control is needed. |
