Re: Spacing between NCE BD20 detectors

Bill,?
I don’t know all of the in’s and out’s of your layout. ?NCE has an article on their website that discusses a BD20 detection challenge that reads similar to yours at this link,?. Hope this helps. ?

Allan,

I've tried a variety of "winding" strategies, but without success.? When I talked with NCE's technical support fellow the other day, he was pretty skeptical about the feasibility of 25' blocks.? He suggested that the only viable option was installing a POT on the BD20, which I haven't yet attempted.? In the meantime, I'm double-checking all my wiring.? My experience (successfully) building a test-bed tells me that it's all too easy to goober up connections.

Hi Bill,
If you haven't tried it already, try putting more than one turn through your BD20.? Literally just loop it around and go through it again.? This increases sensitivity of the BD20.? I don't think you need multiple detectors in a block.? Check the BD20 instructions for multiple turns through it.

Spacing between NCE BD20 detectors

 

I want to keep my Atlas signal blocks coterminous with my railroad's four power districts, each of which is approximately 25 feet in length.? Initial experimentation indicates that placing one NCE BD20 in the middle of a block will not detect a train. Can anyone in this group offer any guidance on using multiple detectors in a block?
Re: Relay

 

If you have a balloon or a wye, you will have a reversing section.? One way to effect the polarity change for these tracks is to use a relay attached to the switch machine at the throat of a balloon or wye.? aka a "throat controlled relay."? For more on reversing, see my website at:??? Also, see my column in the April 2021 issue of Model Railroader.

What is a "throat" controlled relay? I did a Google search of the net and could not find an answer.?

Thanks

If you want it to be automatic you need to provide a location sensor near each end and something like the NCE mini-panel to generate the equivalent of button presses to command the action. If you are doing this for loco break-in it would help to use the same loco address.

Re: Peco Crossover

 

Since you said that you swapped the wires to the Tortoise 2 and 3 pins and you got the same result tells me that something is wired wrong.? You can troubleshooting with your DCC power, but it might be easier to disconnect your booster and hook up a digital multimeter set to ohms.? Hook one end to a rail and the other end to your frog.? As you switch your Tortoise, you should expect to get zero ohms as appropriate for the alignment of your points.

Peco Crossover

 

I rebuilt one of my single crossovers using peco unifrog turnouts.? The switch machine is a tortise and the controller is a digitrax ds 64.? After installing the cross over, I test ran several locos.? The cross over is a right hand cross over going from mainline 1 to mainline 2 of a double track mainline.? Locos run through the turnout on main 1 and also cross over from 1 to 2.? However I have a short on mainline 2 when trying to run straight through.? After working on the issue for some time, I found the frog matches polarity with the diverging route (cross over), but does not match polarity on the straight through run.? I have swap the leads to the tortise-pins 2& 3 but get the same results.? I am also using snaps as a wiring harness to the tortise.? Somewhere the frog is only matching polarity to the opposite rail on the straight through route.? Does anyone have any suggestions as to what I should try to do to correct the issue?

Thanks in advance

Hi everyone,
I have a part of my HO layout where I want to just run a train back and forth a distance of about four feet. ?How do I run the train forward, stop it at the end and reverse it and do the same thing on the other end? ?I am using NCE's DCC control system.

Thanks for your input!!

If one of those has closed up ... most of the way but not all the way ... that
can cause a short/intermittent short.? The way those gaps get closed is
usually due to cleaning track and using too much pressure - "if the rail
moves you are using too much pressure" is a pretty good rule.? Guys will
then say "but it doesn't get clean that way" to which I reply "use more
repeats not more pressure".
