Track and electrical/DCC

Rivarossi DCC project

Fri, 2014-08-22 11:31 — gdparson

I am in the final stages of installing a DCC system into a favorite Mikado HO model and all of a sudden I cannot get power from the tracks. It seems to be from the positive side of the engine... the red wire picks up power (I think) from a spring and brass bushing that rides on the axle of the last set of drivers. I cannot see how the connection is made and yes everything was working fine when I took it apart... Not paying attention is of course part of the problem, other than that...

Makes our model video cab rides look smooth!

PS - okay, so I don't know how to embed the video...

A look inside an LM-2

Want to see what's inside a Rail Pro decoder? Pretty dang complex bit of micro electronics. Made in the USA. Take that China!

DCC Installations Problem

Wed, 2014-08-20 05:01 — akarmani

I am installing a Digitrax SDH164 into a older 2-8-2 steam engine for a friend. I am not really sure what brand of engine it is.  It is an inexpensive engine, but it has a can motor. It runs ok on DC. The start voltage is around 6 volts and the stall amps at full power is .08 Amps (80mA).

How expensive is your track?

Mon, 2014-08-18 22:03 — MikeM

Given the cost of just the rail, roadbed, spikes/solder, etc. how much do you think you're spending per foot of finished track? I'm curious about just simple track, switches/crossings/wiring/etc. obviously add to the cost but I'm just wondering how much folks are spending per linear foot.

How did these ties warp?

Mon, 2014-08-18 16:24 — DrJolS

I've never seen this before. There are three tracks in this staging yard. Photos show the one rail where the condition showed up. Ties are warped up, most easily seen at ties # 3,4,5,6 from the feeder wire, and even better at ties #9,19,11,12.

At the feeder wire there is no sign of distortion from soldering. So why are any ties messed up, and especially why are there a couple ties in the middle of the run that look OK?

 

Soundtraxx Tsunami Sound Start on Engine Select

Mon, 2014-08-18 08:43 — nebrzephyr

OK...I'm pretty sure I've seen someplace that on the Tsunami you can set the sound to come on only when the engine address is selected vs the default which is sound on when track is powered on. I can not find the CV(s) to do that in looking thru the technical reference manual.

Any help would be appreciated. Thanks. Bob

CV Readback Issues JMRI/PR3/Zephyr Xtra

Thu, 2014-08-14 16:49 — jramnes

Greetings:

I suspect I am missing something simple. In the past I have been able to program and read back using JMRI, a PR3, and my Zephyr Xtra. If I recall, I could read back on the main as well. Having not used the program for some time, I find I am no longer able to read CV's through JMRI. I can write to multiple decoders, control the layout including throttles, and start a WiThrottle server successfully. I just can't read back. Any suggestions would be appreciated. 

Thanks, Jim
