arete, but for an embankment with a plateau all that is needed is two
delineating the plateau.  Some may want to relate them in some way, but
purely for
rendering they're two embankments spaced a little apart and sloping in
directions.  I haven't tried it, but I suspect superposing two embankments
facing in
opposite directions would handle an arete type of embankment (such as a
stop butt)
with no modifications required to the renderer.

Wouldn't necessarily need one unless the plateau of the embankment were so
that the embankment would blot out the railway or the railway would blot
out the embankment.
