Signals for dummies

[NW Mailing List]

Carl;
 
The orange loadout happens to be there. Spring has a formal name because it is an interlocked control point. Over on the CV Extension (ex- Interstate) where is it is track warrant controlled, there are places with names like Tank, Miller, Top, Josephine, etc., that just have the place name and no signal, because the dispatcher can tell a crew to work between 'Tank' and 'Miller' and it gives the crew defined limits for the track warrant, since there are no interlocked control points.
 
In regards to the signal question, if I understand you correct, you are wanting to know why in some cases there is a tall and a short mast at one end of the siding and a pair of tall masts at the other end. I cannot recall seeing  a pair of tall masts at one end of a siding unless there are multiple (read three)  targets on each mast. I have most often seen mid-block signals where both masts are tall. Is there a specific siding location where there are mixed masts on one end and a two tall masts on the other end with only one target on each of the two tall masts?

Regards,
Russ

Thanks Russ, Tough choice deciding whether to answer what I asked vs what I meant.  Sorry.  The signal I attached is not the one from Tacoma as you pointed out – my mistake.  That one is actually from Boody (I think).  The signals at the Tacoma siding are as you said missing the lower diagonal.  One thing I find curious it that if I found the right ones this time, they are high/low at one end, but both the same height at the other end. So the location of the Orange loader is called Spring.  I thought it was still Tacoma.  Thanks for that tidbit as well. Carl WoodsRichmond, VA From: NW-Mailing-List [mailto:nw-mailing-list-bounces at nwhs.org] On Behalf Of NW Mailing List

Subject: RE: Signals for dummies Carl The signal in the attached image is at CV459.7, Spring, Va. The east end of the siding starts at Tacoma (CV458.3). The taller signal on the left is for the mainline and the lower set on the right is for the siding to re enter the main as trains move WB. At Spring, there is a coal loadout which has changed hand numerous times and is painted orange.  The lower two diagonal targets are for the notification of the spur into the loadout. Signal indications could include Clear (Rule 281 - High Green), Adv. Approach (Rule 282A - Diag. Yellow over Diag. Yellow), Diverging Approach Diverging (Rule 283B - Red over Flashing Diagonal Yellow) Diverging Approach (Rule 286 - Red over Solid Diagonal Yellow).  If the lower diagonal signals are not present, as is the case for the EB signal at Tacoma, this all changes.

I’m interested in understanding how it would be used and what the signal at that location coming from the other direction would look like and how it is used. I’d also be interested in any documentation explaining (again for dummies) the various aspects and the rules associated with them. Carl WoodsRichmond, VA
