When the resident construction engineer was looking for busy work for his inspectors during the winter break in construction, he would send a couple of them out with a pickup load of rails, a couple of 16 pound sledges, a cloth tape, a right-angle prism and a set of plans that showed right of way breaks plus or minus.

Probably 2/3's around here were set this way.
Why do some have an 'X' cut/chiseled and some do not?

Maybe, maybe not. I think every situation would need to be judged on the evidence recovered.
