I have a Real dummy Question, But what better place to post it hence Stupid Questions.

Here's the signal your approaching, it is a Tripple Block absolute, hence 3 displays mounted ontop of each other exactly perpendicular...

ok screw the sophisticated language, im getting myself confused... Three lights on top of each other, absoloute signal, it Displays:

(top) RED/RED/YELLOW (bottom)

According to YOU what does that mean, and what action would you take.

Now i know what this means, but for every person on this eart, there seems to be a different name for it...

Found a neat page that shows the NORAC signal indications and basic rules therefor.

http://raildata.railfan.net/java/DivRte/NORAC.htm

Although every railroad is a little different in how they use signals, the basics are pretty much the same (ie, red=some form of stop, etc). Of course, this doesn't address specific interlockings or other special situations, but it might help understand what's going on, especially for the signal novice.

Without going to any rulebooks, I know of three possible names for red-over-red-over-yellow, depending on the railroad:

Diverging approach: proceed on diverging route at prescribed speed, prepared to stop at next signal.

Slow approach: Proceed at slow speed [which then must be defined in the rules] prepared to stop at next signal.

Restricting: Proceed prepared to stop within half the range of vision, prepared to stop short of trains, engines, etc., etc.

I certainly wouldn't want to be moving faster than about 20 m.p.h. when passing that signal (and that would be 15 on eastern railroads, most likely).

Excellent CshaveRR, Thats exactly what I was wondering, Because I know it as a Restricting Signal when going into the yeard. But I have heard other names for it, So I was wondering what It meant elsewhere.

thanks Larry for the NORAC site.,

I can answer that, the maximum up here is 15 MPH.

On our railroad (for which the name of that signal would be Diverging Approach), a Restricting signal is given by a Lunar White light in the lowest position.

However, if you're watching trains on the station platform at Elmhurst, and see red-over-red-over-yellow on the home signals east of there, you have a train heading into the yard. There is no "next signal" per se, so I presume you have to be prepared to stop at the next switch. The signal is capable of displaying a Lunar White aspect, which I suspect is controlled by the dispatcher to permit a second train to follow a preceding train in the same block...at restricted speed, of course (it's nice for the train-watchers when we have that problem![^]).

Weiner was pretty specific with his definitions.
An articulated locomotive was one in which both of the driving wheel frames could swivel out of line from the boiler. This includes Garratts, Shays, and a variety of other types.
A semi-articulated locomotive was one in which one of the driving wheel frames could swivel out of line with the boiler but the other driving wheel frame could not. This includes Mallets and most North American simple articulateds.

The what is the difference between a Mallet and an Articulated Locomotive? Aren't they the same thing???

As posted earlier in the thread - A Mallet is an articulated locomotive, but an articulated locomotive isn't necessarily a Mallet.

There is a great explanation by Oliver Trozk posted at 13 Jan 2004, 04:27:07, which is on page 34 of the thread.

On the road i run a red over red over yellow is restricting not exceding 20 mph.

Wow this is sure a long thread. red over yellow is restricting here as is red over red over yellow on a 3 headed signal.

[CSSHEGEWISCH]

Responding to my earlier posting, a Mallet is a compound semi-articulated locomotive based on Wiener's definition. Most North American semi-articulated locomotives of similar layout were simple, and were therefore not Mallets.

In a Mallet, steam was admitted from the boiler to the high-pressure cylinders, usually the rear ones. The steam was exhausted from the high-pressure cylinders to the low-pressure cylinders, where it was used again and then exhausted up the stack.
In a simple articulated, steam was admitted from the boiler to all four cylinders, where it was used and then exhausted up the stack.

Congratulations, Nora! This thread of yours will probably break 10,000 viewings by the end of the day!

There's a lot of valuable education in here!
