   On-board use of braking energy in diesel-electric stock  evaluated  
Modern diesel-electric vehicles can be equipped with the capacity to use some of the energy recovered during braking for auxiliary and comfort functions.
Technology field: Regenerative braking and energy management
close main section General information
  open sub-section Description
close main section General criteria
  close sub-section Status of development: in use
    (no details available)
  Time horizon for broad application: 2 - 5 years
    (no details available)
  Expected technological development: basically exploited
    (no details available)
    Motivation:
    Energy saving
  Benefits (other than environmental): small
    Brake resistors produce less heat to be cooled away on board.
  Barriers: low
    (no details available)
    Success factors:
    (no details available)
  Applicability for railway segments: medium
    Type of traction:  diesel
    Type of transportation:  passenger - main lines, passenger - regional lines, passenger - suburban lines, freight
    Feature is limited to diesel-electric stock.
    Grade of diffusion into railway markets:
  Diffusion into relevant segment of fleet: < 5%
  Share of newly purchased stock: (no data)
    Currently, the ÖBB procurement of the 2016 locomotives is the only major purchasing project of diesel-electric locomotives in Europe.
  Market potential (railways): medium
    Whereas the replacement of the first post-war generation of electric locomotives has already taken place, there is major potential for new diesel-electric locos in Central European and other fleets within the next 10 years.
    Example:
    ÖBB 2016
