I took a quick look through my slides that had already been scanned, coming
from the 1969-1975 period. Very few had signals in the background, so the
small sample size could easily be unrepresentative. For masts there appeared
to be more signals mounted on the LHS (looking at the target) than RHS, but
there were examples of both. I could not discern any obvious reason for using
one over the other. If they were mounted on bridges or cantilevers, RHS of the
post seemed more common.
I only noticed one picture of a mast with staggered heads so will refrain from
any comment on those.

Thanks Don.So if the lights are in line vertically you can have the targets
RHS or LHS of the mast. What would determine what side of mast you position
them? Is there shall we say a default side?. Upon more reading etc I found out
to since I model to mid 60s I should be using UCOR rules not CROR rules. Do you
have a quick summation as to when use interlocking or block type signals………..i
am a bit confused on interlocking terminology? This is very indepth subject and
being an old fart I am getting a bit flustered. Thanks for your help its
greatly appreciated.Steve

Subject: RE: [cpsig] What side of mast for signal target
Position of the signal lights on either side of the mast does not affect
signal aspects, so long as they are all on the same side. What does matter is
when there are two lights which are staggered. When in this position, two red
lights mean the signal is permissive and indicatse STOP AND PROCEED. When the
lights are aligned vertically then two red lights mean the signal is absolute
and indicates STOP (i.e. stop and stay).

Subject: [cpsig] What side of mast for signal target
Guys i have been fumbleing my way through the CROR aspects for signal lights
making some model signal lights.I was using the 2007 trackside guide for
location of targets on mast.For instance rule 405 shows green and red target
below and above each other on the RHS of mast yet when i look at other material
this rule and others shows targets on the LHS of mast. What am i missing here
and need to know?. I noticed a few of the materials i was researching showed
targets on opposite sides to the 2007 guide and other materials i was reading.
Not sure and do not want to assume that targ ets vertically placed can be
placed either left ot righthand side of mast. I think i am missing some info
here. .Thanks for any insight to my question. I have gone and made one stand
with vertical aspects ot targets on the RHS of the mast and dont know if thats
correct.Thanks steve
