Bear in mind that in the real world, arresting devices such as described here
only last for one or two substantial collisions before succumbing to fatigue
and shear.
I would suggest building your arrestors so that they "break-away" near the
base when forced to absorb great impacts (I picture a structure that's
anchored between ties with 4 2x6 slopes [two pointing uptrack, two pointing
down, with at least one tie between the two sets of mounting points] with the
arrestor bridging the gap between mounting points, it should break away if
impacted with too great a force, leaving the mounting points below the level
of the trucks.) Coupled with your current knowledge of how robust such a
construction needs to be, it should be childs play (sorry, couldn't resist) to
build an arrestor which will stand up to a few collisions before needing to be
maintained. (This also provides an opportunity for yet another specialized MOW
vehicle for the Arrestor Maintenance Crew.)
