Although I never worked on the LIRR (but my uncle was an engineer there) counting poles was a way to judge speed. The line poles are usually evenly spaced at x per mile. Using simple math, one could time how many seconds between telegraph/telephone, or signal line poles. This gave a fairly close figure of speed.

I think the 12 was changed to 15 simply by turning the glass lens on the cab signal upside down. The upside-down 2 became a slightly odd looking 5!

Thank you, everyone involved, for posting this diagram. Knowledge has to be shared to be useful, and this drawing is, most certainly.
