The idea is that each conductor's punch is unique, a signature, if you will. We punch cardstock tickets, cash fares, remit slips, OBS overtime claims, and other things, sometimes in addition to a handwritten signature, sometimes not.
Mine looks like a circle with a line through it (Chuljin, do you care to scan one of your stubs here?
, but I have seen a mitten, a teddy bear missing an ear, a rustic heart, a star, a VW bug, a tree, an X, a spoon, in addition to other not-so-easily-identified shapes.
In theory, your cardstock ticket will be canceled on the top in the vicinity of the C, and your receipt somewhere over your name. In reality, it's wherever we can. When your ticket is canceled, the revenue portion is rendered void, and your receipt is punched so any subsequent conductors will (hopefully) be able to identify the punch as one of that crew's (I know some conductors who will take a seat check and ask each conductor to punch it, so they have a sample of each cut, for comparison.)
Travel light!

edit: some conductors will double-cancel tickets, some only once - it's personal preference, I think, as long as the ticket is canceled.
I was wondering what the deal is with how the conductors punch somewhat complicated patterns into the ticket stubs. I did a short round trip this weekend to visit friends and noticed on the way out I got two punches that look like the letter M or maybe a bat, and on the way home just one punch that looks like a bird's foot. Are they specific to each conductor? Does the number or position on the stub mean anything? Is this just a bit of old railroad tradition that lingers on or does it still serve a useful purpose?
