Introduction

Program TRC_QNUMB_TRACK calculates the track alignment quality of a track written in trac-, trax- or trax_wdesign- format. The alignment quality can be evaluated according to CEN Technical Committee 256, UIC-518, EN14363 or the Swedish Banverket norm BVF 541.60.



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.


EVALUATE_TYPE
Type of evaluation.
Following types are valid:
UIC_518 = Evaluate the track according to working group 10 Vehicle/Track Interaction of CEN Technical Committee 256 Railway Applications. The evaluation is the same as in EN14363.
MAUZIN = Translate the track to mauz-format and evaluate the track quality according to trc_qnumb_mauz which follows norm BVF 541.60.
Declared= Character*12    Default= 'UIC_518'

DX
Equidistant step in X-axle.
If the X-axle in file INFIL not have equidistant steps. The user can force an interpolation to take place before calculation starts by setting DX to a value not equal 0.
Declared= Real*8    Default= 0. (i.e. no interpolation)

INFIL
Track data file.
Declared= Character*132    Default= Blank

INFIL_TYPE
Type of track data file.
Following types are valid:
SRA = The track written in SRA-format.
TRACK = The track is written in trac-, trax- or trax_wdesign-format.
Declared= Character*6    Default= 'SRA'

L_INTERVAL
Length of track sections for which evaluation of standard deviation and Q-numbers will take place.
According to UIC518 and CEN/TC_256 WG 10 the length of the sections shall be choosen according to:
100 [m]   For speeds lower than 140 [km/h]
250 [m]   For speeds between 140-220 [km/h]
500 [m]   For speeds over 220 [km/h]
Declared= Real*8    Default= 100 [m]

QNUMB_FILE
Write the Qnumb-table to external file.
If not defined the Qnumb-table will be written to standard output.
Declared= Character*132    Default= Blank

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'

SPEED
The maximum permissible speed for the track.
Valid valus are 80, 120, 160, 200 and 300 [km/h].
Declared= real*8    Default= 160 [km/h]

UTFIL
UIC 518 filtered output track file.
Is only created if UTFIL is defined. Only valid for EVALUATE_TYPE= UIC_518.
Declared= Character*132    Default= Blank (No file will be written)

XSTART_KM
Starting kilometer when analyzing the STRIX-file.
Declared= Integer*4    Default= -1000000000 [km]

XSTART_M
Starting meter in XSTART_KM when analyzing the STRIX-file.
Declared= Integer*4    Default= -1000 [m]

XSTOP_KM
End kilometer when analyzing the STRIX-file.
Declared= Integer*4    Default= 1000000000 [km]

XSTOP_M
End meter in XSTOP_KM when analyzing the STRIX-file.
Declared= Integer*4    Default= 1000 [m]


Example of an input data file

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

##
##      Input data for program trc_qnumb_track 
##

 REMOVE_UCAT_WORK= yes

 EVALUATE_TYPE= UIC_518

 XSTART_KM=   0         XSTART_M= 0
 XSTOP_KM = 1000000000  XSTOP_M = 0

 SPEED= 120             # Valid speeds are 80, 120, 160, 200 and 300 
 L_INTERVAL= 500        # For speeds over    220 km/h
 L_INTERVAL= 250        # For speeds between 140-220 km/h
 L_INTERVAL= 100        # For speeds lower than  140 km/h

 INFIL_TYPE= track

 INFIL= K2_4a25-g-k.trac
 UTFIL= K2_4a25-g-k.trac.filtered
 QNUMB_FILE= K2_4a25-g-k.qnumbr
