Norwegian shunting engine Di5

Example of Norwegian shunting engine Di5 with two shunting gears. This is modelled by two different power modes, which differs only by the tractive effort in low speed range. From the two values @maxTractiveEffort and @tractivePower the tractive effort per speed can be concluded considering the typical effort curve of vehicles.

Summary:

  • a minimum identification
    • code only
    • no classification
  • no payload – tare, brutto (timetable) and maximum weights are equal
  • two traction-force-curves

Norwegian Class 93 Diesel Multiple Unit

Example of Norwegian Class 93 (Wiki banner.png) Diesel multiple unit (Wiki banner.png) with tilting technology. The <tractiveEffort> curve is described by a <segmentTable>. The <drivingResistance> is also defined by a <segmentTable>.

Summary:

  • passenger-specific properties
  • several identifying values (code, manufacturer, operator, vehicle ident no.)
  • general power description and tractionforce-curve with para- and hyperbola
  • difference between adhesion mass, tare, brutto (timetable) and maximum weight
  • tilting technology
  • running resistance as a formula
  • Class 93 diesel multiple unit in NSB colours at Hamar station, Norway
