. . . . . . . . . .If my memory serves me correctly,they [ 
telephone/telegraph poles] were spaced about 80' apart. I can remember old 
head engineers using them to calculate train length. Of course back then 
most cars were 40 footers and every pole was 2 car lengths.

This sound like a rather inexact technology.  A car's effective length in a 
train is not its inside length;  it's from inside pulling face of coupler on 
one end to the same point on the other end, probably about 45 feet for a "40 
foot" boxcar.
