Speed harmonisation is a means to improve line capacity especially where demixing fails. The measure consists in adapting the speeds of all trains running on the same track. Increased traffic fluidity can have energy efficiency effects.

Description

|
|
|
Speed differences of trains running on the same line reduce traffic fluidity and line capacity. An effective means to improve the situation is demixing. In all those cases, where demixing is not possible or has reached its limits, speed harmonisation is an alternative option. In situations where fast freight trains and fast passenger trains are operated on the same line, the speed of passenger trains may be reduced to the average speed of freight traffic in order to improve local traffic fluidity.
The case of "downward" harmonisation, i.e. making fast trains slower, is more common than "upward" demixing. The following evaluation refers to "downward" harmonisation. |
