Herre are some pages from the 1962 Canadian Operating Rules. They cover signal indications.
Page 2 of the rules
Third and last page.
Thats good information David. Thanks for posting. I imagine the US and other countries used something the same or close to.
Restricted speed: a speed that will permit stopping within one-half the range of vision. And in no case exceeding slow speed.
Slow speed: a speed not exceeding 15 miles per hour.
Medium speed: a speed not exceeding 30 miles per hour.
Limited speed: a speed not exceeding 45 miles per hour.
Some of these rules have been changed since then. I put the new rule numbers in pencil. The term "approach" now seems to be "Stop".
unlit lamps are to be taken at the most restricting meaning, usually red.
The signals are speed signals only; they do not indicate routes. A lot of them limit speeds through switches or interlocking, then permit a higher speed to the next signal.
Signals with both heads on the same side of the pole are interlocking signals. Signals with heads on opposite sides of the pole are block signals (second pole in rule 281).
That's great David!! Thanks for posting it!! I'm going to download those pages for reference if you don't mind :thumb:
I would have to say they are somewhat similar to where I run, except for the station protection signal and the take or leave siding signal. One noticeable missing signal I see a lot of is the Advance Approach Signal. A flashing yellow aspect that basically means to pass the next signal (approach) not exceeding 30 mph and be prepared to stop at the second signal.
Hoghead: I took these out of the 1962 revision. The Canadian Trackside Guide has the current Canadian rules -- All the numbers have been changed and the station protection signals and grade signals have been dropped. There are a lot of additions (I count 30 rules) including 409 Advance clear to stop which is flashing yellow, flashing yellow over red, or flashing yellow over red over red.
(If anyone wants the current version, the Trackside Guide 2005 is Cdn $29.95.)
I saw a comment that the most efficient railway would have every train coming on every signal just as it turned from red to yellow.
Advance Clear to Stop?
The aspect sounds like the same as an Advance Approach.
I take it means to stop at the second signal?
Advance clear to stop
"Proceed, next signal is displaying Clear to Stop, be prepared to stop at second signal"
The advance approach will lead you into an approach and finally a stop signal (or on occasions - Restricting)
That clear to stop name really throws me for a loop
Clear to Stop
Rule 410 Clear to Stop "Proceed, preparing to stop at next signal".
Signal shows Yellow, yellow over red, or yellow over red over red.
I just tells 'em, I don't decide 'em.
