Tom, It didn't have to be exact. As Bob and I have been talking ,it most  
hoggers knew where they would be out of a restriction or yard. It was more a  
reference or reminder to let you know in the fog or rain when you couldn't 
see  much else. While a boxcar might be a little longer than 40' ,a couple 
of tanks  or hoppers would average things out. When your working on your rest 
day in and  day out you learn to help yourself out.

. . . . . . . . . .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.
