Demixing of railway infrastructure |
 |
evaluated |
 |
|
|
| At present many railway lines have a mixed operation, i.e. trains with big speed differences run on the same lines. In an effort to increase capacity without investing in additional infrastructure, infrastructure operators try to “demix” their infrastructure by restricting trains to specific tracks according to average speed. Improved traffic fluidity may reduce energy consumption.

Poor traffic fluidity substantially increases the energy demand for train operation. Since many train conflicts are caused or aggravated by trains running on the same track at different speeds, the demixing of railway infrastructure has a certain potential for improved energy efficiency. However, since the main motivation for line demixing is to increase capacity, in many cases, traffic fluidity gains through demixing will be mostly or fully compensated by increased traffic density. |
