Table of Contents

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 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.
MAUZIN	=	Translate the track to mauz-format and evaluate the track quality according to trc_qnumb_mauz.

Declared= Character*12    Default= 'UIC_518'

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*4    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*4    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:
