Modeling vehicles for other gauges than 1435 mm

• Running preprocessor KPF
  Set the following input data parameters to their appropriate values: bo2, gauge_to_origo, iwheel_spacing and iwheel_to_origo. The parameters are described in Wheelset-track geometry in the KPF Uses Manual.
• In the tsimf-file the key-variable bo_ must be updated.
  The value of bo_ shall be set equal to (gauge+2*gauge_to_origo)/2.
• Gauge irregularities
  In the track irregularity files trac, trax and trax_wdesign the gauge signal column #4 contains the quasistatic value of the gauge.
  In order to handle the gauge correct the track data file must be modified, so the quasistatic value of column #4 corresponds to the value of the gauge. Also define the key-variable gauge_average equal to the new gauge.
  If any track data file for the new gauge not are available, it is possible to use a track data file for nominal gauge and fake another gauge by setting the key-variable gauge_average equal to 1435.
  Please look under Modify track gauge for more explanations of the key-variable gauge_average.
• Designed cant
  By dividing the designed cant with 2*bo_ as described under Designed track geometry, the cant will automatically be translated into radians independently of the gauge. Therefore the designed cant will not be affected by the gauge.
• Cant irregularities
  In the track irregularity files trac, trax and trax_wdesign the cant signal column #5 is the height difference between left and right rail. If the key-variable CMtrac is defined as described under Track irregularities above, the cant errors will be translated into radians automatically.
  If any track data file for the new gauge not are available, it is possible to use a track data file for nominal gauge and fake another gauge by setting the key-variable CMtrac equal to 1/1500.
