   Light coach interior equipment  evaluated  
Interior components such as seats, wall panelling and windows offer considerable potential for weight reduction. Possible measures include both the procurement of new stock and the refurbishment of old cars.
Technology field: Mass reduction
open main section General information
close main section General criteria
  close sub-section Status of development: in use
    (no details available)
  Time horizon for broad application: now
    (no details available)
  Expected technological development: dynamic
    New developments will come mainly from new materials, especially fibre-reinforced polymers and sandwich structures.
    Motivation:
   
  • Weight reduction for reasons of vehicle dynamics
  • Energy saving
  Benefits (other than environmental): medium
   
  • Improvement of vehicle dynamics
  • Lowering of center of gravity
  • Reduced axle load
  Barriers: low
    If lightweight interior equipment combines mass reduction with high aesthetical value and passenger comfort, barriers are low.
    Success factors:
    (no details available)
  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
    Weight reductions in interior equipment are not only an option for new stock but may be part of retrofit measures on existing stock.
    Grade of diffusion into railway markets:
  Diffusion into relevant segment of fleet: not applicable
  Share of newly purchased stock: not applicable
    Weight reduction of interoreqiopment is a continuous process. Therefore a general grade of diffusion cannot be given.
  Market potential (railways): high
    (no details available)
    Example:
   

Copenhagen S-trains

The joint development project of DSB and the Siemens/LHB consortium included a thorough assessment of the optimum solution for interior equipment combining lightweight with LCA targets.

Refurbishment of coaches at SBB

In a coach retrofit project at SBB, the total weight was reduced by 2,0 tons from 44,0 to 42,0 tons (~ 5%). This was achieved by lighter setas and by elimination of one toilet.
