DC - Electrical

DC turnout signal question.

I'm working with DC. I have a Walther's turnout that is moved via a Caboose Industries ground throw. I would like to have a couple of LEDs on the panel to indicate the direction the switch it thrown.  The leads from the ground throw do not give a reliable connection to use. I considered getting the signal via the track, but it would only work if the track were energized. Is there a way in DC to check continuity between the rails of the switch and have that come back to the panel?

TIA,

Grain of Wheat bulb hookup

Hello. A question about grain of wheat bulbs. I have a small mining tunnel that would accept a grain of wheat bulb for interior lighting of the tunnel. Never have used these bulbs before; but know they will take a very small current. I want to hook them up to the Accessory terminal of my power pack and use, for the time being, a Atlas slide switch to turn the bulb on and off. I recognize that it would literally be on for just a second or for however long I hold the slide switch down, but that is really for testing purposes.

New product announcement - the Signal Tester

We are pleased to announce a new product to our line, the Signal Tester. If you have LED-based signals that you want to test or if you have a signal with unlabeled magnet wire (e.g. BLMA) then this is the product you need! You can also use it to show off one of your signals for simple display purposes. The Signal Tester uses a 9V battery (not included) for power and is simple to use. More information about this product can be found on our website at http://www.logicrailtech.com.

DC sound, NOT DCC sound

I've got several very nice diesels in which I would like to install sound.  I am aware of the MRC 1000 series, which I believe is no longer being offered, except on eBay.  My understanding of how they were produced is that they had a plug that was comprised of about five wires.  Since the module is wireless I don't understand why any more than two wires are necessary, each to pick up power from a shoe going to a wheel on a track.  I have assumed that in order to install one, then, you simply have to snip off the plug and find out which wires take the

Feeding the track power?

 

I have a little trolley layout that was a straight  8 feet long point to point layout, center fed for DC power. I added a loop and some sidings that add about 15 feet more track in a 4 by 5 foot additional table adjacent to the long 8 foot original layout.

 

Wire guage

Ok, wiring up some track. Feeder wires are 20 AWG and run about 10-12" where they connect with 14 AWG bus wire. When I wire up switches to turn on/off the block, I should continue the 14 AWG and heavy duty toggles switches? Now, when I run wires for the signaling (mostly LEDs indicating switch position) I think I can use thin 22 AWG (like telco) wire. This will be isolated from track power, just enough to drive the LEDs. Is this logical thinks or am I missing something?

Signaling for DCC

How do you restart a DCC loco which has stopped at a signal without doing it manually? I think I read somewhere about switching sig. track to DC currant while train is stopped then back to DCC power when signal turns green. Can somebody please assist. If DC currant is applied then at what voltage?

 

Documenting the wiring of the layout.

When I was a member of the Abington Lines Model Railroad Club a LONG time ago, the member that was in charge of the wiring was an EE. As such we had very good documentation of where each and every wire went and what it did. He did this with a combination of a spreadsheet and software that produced a wiring schematic. I was wonfering if anybody does this and what software they use?

I am working on adding computer control to my little point to point trolley layout. The controller is the Ardunio UNO MicroController board. I have it all worked out for connectivity and just finished bench testing the components and the program. It is going to work!
