Automated train operation does not automatically improve energy efficiency. However, an automatic control offers various options for optimising train operation both on a single train level and a systemic level. This includes: - Timetable optimisation: synchronisation of braking and acceleration phases of consecutive trains in order to maximise regenerative braking
- Optimised driving styles: energy efficient speed control and/or coasting
- Increased traffic fluidity through centralised train control
On the metro line 14 in Paris, RATP has integrated synchronisation of acceleration and braking into the timetable design. A general quantification of these effects in terms of saved energy is not possible. |
