The New Northern Central

[Ed Kapuscinski]

Slow progress with my floor project going on simultaneously, but I gave my knees a break on Sunday for some more benchwork.





The foam is just sitting there for now, so it's a bit of a lie.

I like the way the foamcore plug in the old door area makes that a little less insane looking. It'll all be covered in backdrop eventually, but for now, it at least looks a LITTLE better.

I remembered that I still had this photo sitting around. It's actually probably going to be used in this spot again, since it's the right scenery for the spot (jail and all).



It's not much progress, but at least it's something.

I've been thinking about one of the interlockings on the layout while doing flooring.

So here's my conundrum.

In reality, the track exiting the layout on the left would be the unsignaled yard lead. So there would be signals on the main, on route from the yard through the crossover, and on the passing siding on the right.

That track shouldn't be signaled because it'd be annoying for yard crews working that end of the yard to always need to get the signal to switch.

However, in reality, it's going to be a second track into staging, for which I really want to give signal indications.

I'm leaning towards signaling it for ergonomics sake (ie, making it easier for crews heading into staging). What do you all think?

Signal it.

You should signal it, but you should also make provisions for a yard limits lock out that would give the yard master control over the approaches to that section. The signal wouldn’t be activated until the yard master granted approval to a train to approach the yard.

Agreed, it should be sginalled.  You could put a dwarf signal in front of the top turnout in the image that would control access to either the lead into staging or the crossover to the main.  That would hold trains clear of any switcher working that end of the yard until the switcher got out of the way.  The switch crew could be required to call for time limits to work to avoid too much delay to the road trains.

Clearly you haven't finished Dave Abeles book on signals yet - theres actually an example pic of this in there somewhere.

Signal it.  Use something not standard (dwarf, lower quadrant semaphore, ball and rope) to emphasize the point.

I have, actually, and that factored in to my decision to say F-prototype adherence, it's getting signaled to make life easier for everyone.

Thanks everyone for the input.

Just remember Ed's Law

Ed,

Like this.


A dwarf signal and dispatcher controlled switch.  When the switch is lined for the switching lead the signal is always flashing red (restricting), when lined for the main, yellow (approach).  This way the yard job never has to contact the dispatcher for a signal when switching the lead.

If he wants to amaze and confound visiting operators, it could be lunar/yellow, as well. Saw lots of that protocol in the era he's modeling. There are a few points on my layout that will get this treatment.

Thanks for triggering my human factors training from Clemson    it’s amazing what some people think of (to be fair I’ve come up with a couple at work myself)

Mike,

On the UP at least, a yellow over lunar would be "Approach Restricting" which would mean the engineer would have to be prepared to be at restricted speed before passing the next signal, unless your talking about a signal from the yard lead to the main.  But at the signal on the main before the signal into the yard he could have a red over yellow over lunar (Diverging Approach Restricting) that could really mess with peoples minds.

******** BRILLIANT.

Although, using NORAC/PRR signals, it'd just be a \ indication for restricting.



Now that I think about it, when lined for the main it'd be a "slow something", given the switches involved. \

This stuff is fun!

Oh, I meant a single dwarf head displaying yellow OR lunar. I over-use the '/' in my online prose. 

FWIW, I have the UP rule book from my modeling period right here on my desk. You're right, Diverging Approach Restricting would leave them scratching their heads, for sure! I think there's an interlocking/yard entry already on my layout where this aspect would be totally appropriate.

Ahh, OK.

My favorite though is red over yellow over yellow.  Diverging Approach Diverging.
