   Modular train sets  evaluated  
The use of short train-sets which can be combined to trains of variable length raises occupancy and thus allows for a more cost and energy efficient train operation.
Technology field: Increase of load factor and flexible trains

open main section Environmental criteria
close main section Economic criteria
  close sub-section Vehicle - fix costs: medium
    The seat-specific costs are higher for shorter units since (almost) the same transformer and inverter equipment is needed as for a longer unit. The same is true for the drivers’ cabins. An additional cost effect can arise if trains-sets of different length are ordered, especially if the train design requires a tailored solution, as was the case for 5-coach and 7-coach MUs ordered for the ICE T tilting trains. However, the increase in seat-specific investment costs will in most cases be overcompensated by less need for seating capacity due to better adaptation of capacity to demand.
  Vehicle - running costs: significant reduction
   

The running costs per passenger-km are substantially reduced due to

  • Reduced energy consumption
  • Reduced maintenance costs (less rolling stock required)
  Infrastructure - fix costs: none
    (no details available)
  Infrastructure - running costs: increased
    More coupling and decoupling processes are required for train formation.
  Scale effects: low
    (no details available)
  Amortisation: strongly dependent on specific application
    (no details available)
no data available Application outside railway sector (this technology is railway specific)
close main section Overall rating
  open sub-section Overall potential: promising
  Time horizon: short-term
