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:
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 – 1999 and CEN/TC_256 WG 10 – 1999 the length of the sections shall be choosen according to:
Track sections in straight track and very large curves (cd ≤ 40[mm])
| 250 [m] | For speeds ≤ 220 [km/h] |
| 500 [m] | For speeds > 220 [km/h] |
Track sections in curves R > 600[m]
| 100 [m] | For speeds V ≤ 140 [km/h] |
| 250 [m] | For speeds 140 < V ≤ 220 [km/h] |
| 500 [m] | For speeds V > 220 [km/h] |
Track sections in curves 400 ≤ R ≤ 600[m]
Track sections in curves 250 ≤ R < 400[m]
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
