[CBQ] signalling

[qutlx1@aol.com]

Mark,
 
Maybe others can advise if there was a formula to determine when volumes  
required if signals or hand throws governed a movement in a "plant". What I 
can  tell you is what I saw on the "property".
At Mendota,IL the interchange track to the IC was controlled by  
drawfs("pots"). At Rochelle,IL the C&NW interchange track was a handthrow  with 
a 
timed interlock but no drawf. The "199" interchange track was hand throw  but 
controlled by the signal on the mainline signal bridge inbound and by a  
drawf("pot") outbound.
The IC interchange track at Amboy,IL was manual  w/o a signal  but mainline 
xing was signalled.
The C&NW interchanges at West Chicago,IL were all manual.
The IHB interchanges at Congress Park,IL were all signalled with  drawfs.
 
Not sure I have done anything other than cloud the issue.
