Rob -

Block signal N 245.1 is 5.4 miles west of Prairie du Chien, WI (MP 
239.7) and 9.3 miles east of Lynxville, WI (MP 254.4).  The numerals 
on CB&Q signals correspond very closely to the actual milepost 
location, right down to the "tenth of a mile".  The N or S 
designation is, like Archie mentioned, reference to the "N" (north 
side of main) or the "S" (south side of main) and infers double track 
ABS (Automatic Block Signal) system where there is a "current of 
traffic".  Number plated signals are called "intermediate" signals 
and in "Q" days, the number furthest to the right (and usually to the 
right of the decimal point) always is an even number for eastbound 
signals and an odd number for westbound signals.  N or S on a number 
plate is redundant when you consider the last number to the right 
tells you the direction the signal governs and in recent years, the N 
or S and the decimal point have been removed from the number plates.  
In multiple (more than two) main track territory, such as on 
the "East End" between West Eola and Union Ave. the intermediate 
signal's number plates by "Q" standards would read, main track 
number, followed by a dash, then the milepost (whole) number, decimal 
point and finally, the tenth of a MP (always even for E/B; odd for 
W/B).  A signal on the East End with the numbers "2-36.4" would be 
the signal on main #2 at MP 36.4 governing an eastbound train 
movement (in this case, the eastward approach signal for the absolute 
signal at the West Eola interlocking plant).  The BN/BNSF has dropped 
the dash and the decimal point and the signal number now reads "2364" 
leaving it up to the Signal Dept. to decipher its location if there 
is a problem with the signal indication.  Block signal N 245.1 could 
also appear on the Ottumwa Subdivision of the Nebraska Division near 
Beckwith, IA or on the Brookfield Subdivision of the Chicago Division 
near Coatsburg, IL but what "nails" your photo as being between PDC 
and Lynxville, WI is the Mississippi River in the background.  The 
other two locations previously mentioned don't have a river anywhere 
near that signal location.  Hope this answers your question regarding 
the signal picture?  Can't help on the water tank other than to guess 
between North LaCrosse and Daytons Bluff.
