   Coach insulation  evaluated  
Thermal insulation of coaches contributes to overall energy efficiency of passenger stock. Many measures can be carried out not only in new stock but also as a retrofit.
Technology field: Optimisation of comfort functions

  close sub-section Vehicle - fix costs: medium
    Obviously the costs strongly depend on the individual measures realised. In the case of the retrofit of B 20-73 at SBB, the additional costs for insulation of walls and installation of new glass for windows amounted to 12.800 Swiss Francs (8700 EURO). An additional 800 Francs (550 EURO) was spent for the insulation of ventilation ducts. These costs would be considerably less for a bigger vehicles series.
  Vehicle - running costs: significant reduction
    (no details available)
  Infrastructure - fix costs: none
    (no details available)
  Infrastructure - running costs: unchanged
    (no details available)
  Scale effects: low
    Certain scale effects are to be expected for the retrofit of large vehicle series.
  Amortisation: not applicable
    The payback time strongly depends on the individual measures realised but will typically be short to medium.
no data available Application outside railway sector (this technology is railway specific)
