the right rail, the superelevation would

Description
When this box is checked, offsets can be
typed in.
Often it is necessary to stake out points with
a fixed plan offset and fixed height offset
from a known reference line (track centreline
or rail).
Offsets are applied in the same way, irre-
spective of how the rail design has been
entered, whether the offsets are manually
entered or if library offsets are used. The sign
of the offsets conforms to the offset sign
convention described in "43.6.12 Rail - Work-
ing with Offsets".
