Introduction

Program TRC_STRIX_TRACK transforms files recorded by the STRIX-recording car into files written in trax_wdesign-format. The recording system in STRIX is an inertia based recording system. The format of the STRIX-recordings shall be of type SRA.



Calculation procedure


Gauge irregularities


Vertical irregularities


Cant irregularities


Lateral irregularities


Designed track curvature


Designed cant angle


Designed vertical lift of track center line


Input data

Input data is read in free format, valid separators between the input values are <space>, <comma>, <tab>, <equal sign> or <carriage return>. The commands can be written both in lower and upper case letters. The operation of the program is controlled by the commands described below; some of the commands also need arguments.


INFIL
STRIX-file in SRA-format.
Declared= Character*132    Default= Blank

UTFIL
Result file written in TRAX_WDESIGN-format.
Declared= Character*132    Default= trc_strix_track_UTFIL.trax_wdesign

VEHICLE_DIRECTION
Definition of leading end of the vehicle.
Declared= Character*1    Default= A

REMOVE_UCAT_WORK
Command which controls if the working directory "ucat_work" should be removed or not after the calculation.
Declared= Character*4    Default= 'NO'

XSTART_KM
Defines the first kilometer from where the translation shall begin. Valid values can be obtained from program trc_strix_test.
Declared= Real*4    Default= 0

XSTART_M
Defines the meter within the first kilometer from where the translation shall begin. Valid values can be obtained from program trc_strix_test.
Declared= Real*4    Default= 0

XSTART_UTFIL
Defines the meter where the output file shall begin.
XSTART_UTFIL must not be bigger than 1.e5 or less than -1.e5, because program trc_strix_track is written in single precision.
Declared= Real*4    Default= XSTART_KM*1000 + XSTART_M

XSTOP_KM
Defines the last kilometer where the translation shall end. Valid values can be obtained from program trc_strix_test.
Declared= Real*4    Default= 1000

XSTOP_M
Defines the meter within the last kilometer where the translation shall end. Valid values can be obtained from program trc_strix_test.
Declared= Real*4    Default= 0


Example of an input data file

Following example: Master.trc_strix_trackf can be used as a master file:

##
##      Input data for program trc_strix_track 
##
  INFIL = 85251257.sra
#
  VEHICLE_DIRECTION= A
#
  REMOVE_UCAT_WORK= yes
#
  XSTART_KM= 1   XSTART_M= 808
  XSTOP_KM = 3   XSTOP_M =  60
#
  UTFIL = 85251257.trax
# XSTART_UTFIL= 0
