Is a resistor on the programing track still needed?

Sat, 2014-07-26 09:18 — DKRickman

I've heard of wiring a resistor across a programing track, to assist in programing certain (sound?) decoders.  So far, I've never had to bother, but I'm building myself a proper test/programing rig, and I'd like to know if it's worth including a switch for a resistor.  Is it something that's no longer needed, or does it still come in handy?  Basically, is it worth the effort of including it in the design?

Double check my wiring, please?

I think I have this right, but before I let the magic smoke out of something, I would appreciate someone else's opinion.

Here's what I'm building:

The block at the back will support a test/programing track (18" long), and the block at the front will house whatever switches are needed to control things.

Has anyone installed the new Current Keeper from Soundtrack in an Athearn Genesis GP9. If so how did you make the room for the installation

Someone asked about what was new in the area of DCC sound. We're going to have a first look of the SoundTraxx Soundcar system coming up in a future issue, and I was able to interview Norm Stenzel of TCS regarding their upcoming (now in Beta) WOW Diesel sound decoder -

DCC circuit breaker delema

Most DCC breakers and reversing loops require about 5 amps. of current to cycle. The MRC Prodogy Advanced  system uses 3.5 amps. So how do I protect my system?

Is there a primer for DCC stationary controllers

Wed, 2014-07-16 04:41 — casenundra

In my quest to computer control a shuttle train I find that I need info on stationary controllers for tortoise switch machines and some info on block detection. Does anyone have a source that a simpleton such as myself can understand?

Good Afternoon All,

I am Pranav, an architect in India, and a model railroader who is trying his hand at his first DCC Layout. Small, I grant you, but so so much fun. Being in India, a country with almost no model railroading worth mentioning, mistakes are time consuming and expensive. I therefore come to you for advice.

Decoder air gaps.

Hi

I'm looking at finally getting around to upgrading my fleet of locos to Dcc sound over the next 12 months.

All look possible to convert, but I have concerns having enough air around the decoders on two switching locos (emd model 40) yes it can be done.

Any thought on the minimum amount of air / clearance around a decoders?
