CHAPTER 5 PROCESS
5-15
LINKING RUNS
Any two or more runs may be joined together to create one long continuous run by using the Link
routine within the Edit header.
1. Select the first Run, (Box1_A) then select the second Run. (Box2_A) Be sure you select
the Runs in the sequence you want them linked. You want the second Run to be linked
onto the tail end of the first Run, so select them in the order you want them to link.
2. Tap or click EDIT/LINK to link these two Runs.
The program will now join the two runs you highlighted, using the first run as the "base" run
and linking the second run to the end of it.
The new record will have the same name as that assigned to the first run but will have a ^L
suffix attached to it, showing that it was Linked. In this example, it will be named Box1_A^L,
and which will now be 500 steps long.
The computer will automatically calculate the IRI of the new Linked run.
3. Select the newly Linked Run Box1_A^L. (This now actually represents both Box1_A
and Box2_A, linked together.) Now select the Run named "Box3_A", and use
EDIT/LINK to link these _A legs together.
Again, the computer will automatically calculate the IRI of the new Linked run.
You have just created the profile and IRI, for the right wheelpath for all three boxes
combined.
4. Select leg _C of the first Box (Box1_C) then select the corresponding leg from the second
Box. (Box2_C) Tap or click EDIT/LINK to link these two Runs. Do the same for
Box3_C, and you will have the left wheelpath profile and IRI.
You are finished. If you select both wheelpaths, you may now calculate the half-Car IRI for the
whole length if you wish, or you may use REPORT/GRAPH to see both wheelpaths overlaid on
one another. If this is a very long profile, you may wish to use SETTINGS/GRAPH SETUP (on
the 2277 Tablet) or TOOLS/GRAPH SETUP (on your desktop PC) to limit the graph to fewer
steps per page. We suggest that you try using either 100 steps or 250 steps. This will make the
details of the profile easier to see.
Note: Arrows show the profile after UNBOXing and Linking.
If there are more than three Boxes, just continue UnBoxing and Linking as described above until
you have linked all the Runs in all the right wheelpath sections, and the same for all the Runs in
all the left wheelpath sections.
Start Point Left wheelpath
Start Point Right wheelpath
End Point Right wheelpath
