And even then, if your tracks are within 2"of a long fall, you should seriously consider erecting a barrier of some kind at the edge, either clear plexiglass, or a robust fence meant to look like it surrounds a field, maybe a hedgrow...even add a healthy half-berm of dirt...anything against which a tumbling and expensive car or engine can come safely to rest.

Or, you can do what many of us do...wait until after your first incident.

Naw! Live dangerously. The best insurance against accidents is good trackwork and careful operation.

In this case, though, blind luck may have also played a hand:
