   Mechatronic innovations for future running gear  evaluated  
In recent years there have been growing efforts from mechatronics to study active suspension technologies for railways based on sensors, controllers and actuators. Mechatronics could revolutionize suspension technologies and considerably reduce train weight.
Technology field: Mass reduction
open main section General information
close main section General criteria
  open sub-section Status of development: test series
  Time horizon for broad application: in > 10 years
  Expected technological development: highly dynamic
  Benefits (other than environmental): big
  Barriers: high
  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
    Grade of diffusion into railway markets:
  Diffusion into relevant segment of fleet: 0 %
  Share of newly purchased stock: 0 %
  Market potential (railways): highly uncertain
open main section Environmental criteria
close main section Economic criteria
  close sub-section Vehicle - fix costs: medium
    At this stage of development, the active running gear will be more costly than conventional technologies, but by the time of acceptance and technological maturity there will be significant reductions.
  Vehicle - running costs: significant reduction
   
  • Reduced energy costs
  • Reduced maintenance: reduced wear of wheels and rails / reduced complexity (Reduced maintenance could especially be an issue for low speed systems (trams, metros, light rail) having tighter curves)
  Infrastructure - fix costs: none
    (no details available)
  Infrastructure - running costs: reduced
    Minor reduction due to reduced track wear.
  Scale effects: high
    High, if introduced on a broad scale.
  Amortisation: (no data)
    (no details available)
no data available Application outside railway sector (this technology is railway specific)
