RE: [CBQ] Another signal question

[GLEN <glenehaug@msn.com>]

As part of my signal research, I found references to the use of 2 blade train 
order signals as early as 1892 on Lines East between Aurora and Burlington.  I 
seem to recall that there were specific instructions related to the use of the 
2nd blade, but I can't find where I filed that information right now.
 
I think the use of the 2nd blade was in lieu of a Caution Card Form (B).  In 
manual block territory, where the train order signal was used as a block 
signal, in certain territories designated in the timetable, a 2nd train could 
follow a freight train with the use of this Caution Card.  I think the 2nd 
blade was added to the TO signal to be used in lieu of the caution card.
 
I will try to find more specific information.  I plan to do more research at 
the Newberry during the week after the Spring Meeting, so I may be able to find 
out something specific regarding Superior.

      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 Gene Tacey
