Rail - Working with Multiple Tracks
Multiple tracks are used when more than one track share a common centreline,
from which all chainages are calculated.
When there are multiple tracks with independent centrelines for each track,
each track is then considered as a single track. Refer to "43.6.9 Rail - Working
with a Single Track" for details on single tracks.
