Talk:North American railroad signals

This page is a disaster, the NORAC stuff needs to be its own page or gone and in its place a discussion of North American signal types and practices.Sturmovik (talk) 18:04, 6 September 2008 (UTC)
 * Ok, whew, I updated the entire page. I don't know what to do with those signal rules tho, I think those should probably be removed.  They are on other pages online.Sturmovik (talk) 01:07, 8 September 2008 (UTC)
 * I need to tidy up that color light section. The classifications I used aren't meshing quite well so I'll tweak that.Sturmovik (talk) 04:35, 11 September 2008 (UTC)

Blurred colours


The yellow lamp at the top of the third signal from the left, looks a bit like a red lamp, due to production limitations.

Very Comprehensive
The information all the signal types is very comprehensive. Wouldn’t it be more appropriate to move that to Railway signal, as the information there is far less detailed? —Preceding unsigned comment added by 131.172.4.43 (talk) 13:21, 16 November 2008 (UTC)


 * Thank you, that generic Railroad Signal page is sort of the domain of the European trainspotter mafia and I don't really want to deal with them. I should probably pull the North American specific stuff off of there as this page is the place for the extra detail.  The top Railroad Signal page should probably be flattened and explain about some of the generic design concepts behind railway signaling as opposed to specific signal styles.

Description of (color) position lights clock positions
The current text says that the lights are at "12:00, 2:30, 4:30, 6:00, 8:30 and 10:30". Is this from any official documentation, or OR? Because all the photos of both plain and colored position lights show lamps at 12:00, 1:30, 3:00, 6:00, 7:30 and 9:00, with optional locations at 4:30 and 10:30... IE standard 1/8th rotation places... 193.63.174.211 (talk) 09:31, 21 December 2011 (UTC)


 * That's referring to the CPL orbital lamps, not the lamps on the main head. Sturmovik (talk) 01:42, 31 December 2011 (UTC)

Flashing signals and fault tolerance, failure mode of relay.
The paragraph in Fault Tolerance about flashing relays does not match any NORAC signal. The for instance, Approach Medium and Approach Limited. The flashing Approach Limited is an upgrade of Approach medium. Most if not all NORAC signals that use a Flashing Aspect are less restrictive than the non-flashing aspect.

Maybe I've miss-read the paragraph but it would seem that the wording is backwards from what it should be?
