Derail keeps unattended cars from wandering onto the main.
Use of 3 way harp to control derail may have been expedient IF that is what it is for.

And would it be typical for a harp to be in the middle position for a derail? (A 2-way stub is either right or left, but maybe a derail is treated differently?)
While we're on the topic, what exactly is the purpose of a derail? Just to keep un-attended cars from rolling down the line? Or to catch run-away trains? Or both?
Thanks,
Jeff.
