I'm going to "go out on a limb" and be subject to correction...or maybe 
ridicule from those more knowledgable than I...but here's what i am going to 
postulate.


You will note that the blades are of different shape and color combinations...


The top set of blades is the TRAIN ORDER SIGNAL...ie...when those blades are in 
the horizontal position it indicates that there are train orders for a train.


The bottom set of blades indicate the condition of THE BLOCK ahead of the 
approaching train.....ie it is clear or there is a train occupying that block.


Example.  A westbound train finding the top blade on the right hand side (as 
viewed from and approaching train) in the horizontal position would indicate 
that there was an order for that train...If the lower blade was in the 45 
degree down position it would indicate that the block was clear ahead was 
clear.  A train finding both blades "down" would know that there were no orders 
for that train and that the block was clear ahead.  


In the conventional configuaration of only one set of blades the blade in the 
stop position would indicate that there were orders for that train or that the 
block was occupied.  In that case if the order was a "19" order  (could be 
picked up on the fly...without stopping)...With that order would be a Clearance 
Form A which would indicate that there were X number of orders for that train 
and the block was clear  and that the train order signal was displayed "FOR 
FOLLOWING TRAINS".  


If my assumption is "in error"...I would like to hear from someone whose 
experience and/or "solid knowledge" of this matter who
 would explain.l

"PLease be advised" that I am aware that branch line trains running between 
Edgar and Superior would require orders at Superior before leaving and that the 
lower set of blades might govern that operation...but I really don't think that 
that is the case...Usually in those cases the 
timetable or "Special Instructions" would read..."No train order signal at 
Superior...or....Train order signal at Superior does not govern trains on the 
Edgar-Superior Subdivision.


The use of the TO signal as both a block signal and train order signal was the 
usual arrangement on most railroads, but there was a potentially hazardous 
possibility under this arrangement.   A  head on collision east of Norton 
Kansas on the RI in the 1940's with fatalities resulted from an improper 
handling of the TO signal/block signal.  I'll not go into it here, but the 
details are available on the ICC website.

All,
Found another one that you signal gurus might be able to answer. This is an 
unusual signal at the depot in Superior Nebraska. The top one would be the 
train order signal but what is the bottom one for?
Thanks in advance
