   Energetic optimisation of timetable  evaluated  
Despite strong constraints put on timetable design, many timetables offer some degrees of freedom which can be used for improving energy efficiency of train operation.
Technology field: Energy efficient driving
open main section General information
close main section General criteria
  close sub-section Status of development: in use
    The integration of energy issues in the timetable design is not common in railways.
  Time horizon for broad application: in < 2 years
    (no details available)
  Expected technological development: dynamic
    Powerful optimisation algorithms and simulation programmes have to be developed to optimise a timetable under given restrictions.
    Motivation:
    Energy saving
  Benefits (other than environmental): medium
   

Depending on the optimisation strategy win-win situations can occur:

  • Increased buffer times increase running time only slightly but may improve overall punctuality considerably.
  • The elimination of low-speed sections reduces running time
  Barriers: medium
   

Other priorities

Timetable design is a highly complex task in which numerous restrictions and constraints have to be taken into account. Energy efficiency obviously has a low priority in this context.
    Success factors:
    Focus communication of such measures on win-win situations to be achieved (cf. Benefits).
  Applicability for railway segments: high
    Type of traction:  electric - DC, electric - AC, diesel
    Type of transportation:  passenger - main lines, passenger - high speed, passenger - regional lines, passenger - suburban lines, freight
    (no details available)
    Grade of diffusion into railway markets:
  Diffusion into relevant segment of fleet: not applicable
  Share of newly purchased stock: not applicable
    (no details available)
  Market potential (railways): not applicable
    (no details available)
    Example:
   

Timetable optimiser (TTO) as part of the Metromiser
