For the real anoraks, here's UP's official spike patterns for their tracks, it's quite modern but other than the double shouldered 8 hole tie plates I suspect much is applicable back to the 60's.
For reference, field side is the outside of the track, I.E toward the cess or other running rails, gage (gauge!) is between the rails. Each pattern shows the most common four types of tie plate in use but the most ones I've seen in real life and in photos are the top left 6 hole and bottom right 4 hole. The 8 holes ones I'm presuming are for heavy main lines and most of those that I've seen have gone over to concrete ties and Pandrols.

A few days back there was some discussion about industrial leads being on a grade, UP has a preferred set of parameters for that too.
