Re: Atlas signal - Tortoise Interlocking

Hi Bill,

I reviewed the Atlas schematic you supplied and also went the Atlas website to learn a little bit about the Atlas Signal Control Board (SCB).  I found that it does not control the Atlas switch machine or Tortoise as you desire.  Rather, the Atlas switch machine or a Tortoise provides input to it.

The blue wire you see on the Atlas schematic that goes to the common on the Atlas switch machine would be attached to terminal 4 on a Tortoise.  The two green wires shown going to the Atlas switch machine go to terminals 2 and 3 on the Tortoise.  If you get the wrong aspect displayed, swap the wires going to 2 and 3.

You can control the Tortoise with DCC via an accessory decoder like made by NCE or Digitrax or through any traditional means of controlling a Tortoise switch machine. For more on controlling Tortoise switch machines, visit my website at:  http://www.wiringfordcc.com/sw_ctl.htm

May I enquire why not please?  Surely attachments are the quickest and easiest way to demonstrate you problems/solutions.

It's right under Photos on the left menu when you are in the group.

The warning about not using common rail refers to those using multiple boosters and auto reversers.  Do you have any reversing sections?  Are you using multiple boosters?  If the answer is no to either of these, you are okay.

Hello Allan:

The Toy Train group has switched to allowing attachments. It is really nice to have a picture in the email and not have to search for it. They still have the photo and file sections. It doesn't seem to have caused any problems.

Just a thought.

Thanks, Carl.

Atlas signal - Tortoise Interlocking

Bill Wilken
 

Atlas has published an excellent wiring diagram (see attached) showing
how to create an interlocking connection between its two-headed signal
and an Atlas switch motor. I want to substitute a Tortoise switch
motor for the Atlas switch motor, but do not want to proceed until I
have a clear understanding of how to wire the Tortoise to the Atlas
control boards. Among other things, I suspect that in-line resistors
may be required, but have not idea of what type.


Re: Converting from DC to DCC with selectable power

Greg Harter
 

Our club (Columbus Area Railroad Club) in Indiana, operates a large HO layout with both DC and DCC.  We have several mainlines, with crossovers, and each mainline can separately run either DC or DCC.  If two mainlines with a crossover are operating on the same power source, the crossovers with work.  If one mainline is on DC and the other on DCC, the crossovers will not operate.  

If both mainlines are on the same power source, and the crossover is activated, and then one of the mainlines is switched to the other power source, the crossover (automatically) reverses back to mainline operation only.  We presented a clinic on this at the Indy Convention a couple of years ago.  We have never had a problem with this operation.

Re: Converting from DC to DCC with selectable power

As long as you have only one system active at a time you will be fine.
That means the whole layout has DCC selected, or the whole layout is connected to DC.
Make sure the Master Switch is a DPDT Center Off, or is a “break before make” type.
Then the common rail is OK.

Re: Kato 90 degree crossing track

My experience with HO Kato and its 90 degree crossings says that just power the track as "usual" and there will be no problem - using unijoiners as designed.


Peace,

Hi All,

I am exploring the possibility of having a branch line cross my double track mainline at a couple of spots on the layout. I have to use the Kato N Scale 90 degree crossing track pieces connected to each other for this. The branch line is single track. Here is a picture of what I am exploring.

https://drive.google.com/file/d/1sms65rxI1sFjED4EwAkFFwM_rPNF3KaI/view?usp=sharing

I can feed power from all 6 directions but I think I will need to add feeders to the unijoiners that join the 2 actual crossing track pieces. Am I correct? Without this, I am guessing that the train on the branch line won't have power where the 2 crossing track pieces join.

Thanks for any suggestions.

Re: Converting older steam loco to dcc a scale

Gary Chudzinski
 

The Soundtraxx Tsunami2 and Eco's (if you can still find them), 2 Amp decoders are perfect for S gauge!  Of course, earlier Am. Flyer loco motors need to be converted to low Amp DC motors.

Re: Converting older steam loco to dcc a scale

Hi Rob,

I don't know that there are any decoders specifically made for S scale.  I did a quick check for you on the Soundtraxx website.  Here is a link for you and their recommendations:

https://soundtraxx.com/reference/decoder-selector

I highly recommend going with a decoder that has sound capability.  Sound brings model trains to life.  Also check out TCS's WOW! sound decoders and ESU's LokSound.  These are all popular with modelers.

You can't wrong using a decoder for O-scale.  If your motors are high efficiency, you might be able to use HO scale decoders.  The main thing is that their stall current doesn't exceed the capability of the decoder.   Put your loco on a test track using "old-fashioned" DC and briefly hold the loco so the wheels don't turn.  Measure the current it draws.  If this is within the current limit of the decoder, you can use a smaller HO locomotive.

Converting older steam loco to dcc a scale

I have a couple of older s scale locomotives that have new can motors installed and was thinking about updating to dcc. Question is decoder selection. Is there a preferred way to go in s scale? This will be my first dcc layout. Thanks for the help.

Re: MegaPoints Controllers

Hi Lou,

I don't know if they DS-64 can store any routes.  Definitely routes go in the Digitrax Command Station.  I've used the DS-54 (predecessor to the DS-54.)  Programming wasn't too bad.

Control panels stick into the aisle and take some time to wire.  Many modelers don't have wide aisles in their homes.

Good luck!

Re: MegaPoints Controllers

 

I have been very happy with the Swedish Mollehem Sevo 5.  It is very affordable, easy to set up with their Bluetooth interface and Android app, has built in relays to supply point power, sufficient inputs for local switch control as well as Loconet control.  I think it has route control but I use JMRI for that.


Re: MegaPoints Controllers

Alan,

Thanks for the info I'll take a look at the LCS switch machines. I did some more research and it seems that the Digitrax DS64 and the DT400 throttle can be setup for routes; the advantage is no control panel taking up aisle space; the disadvantage would be added complexity in programming. I would be interested in hearing from anyone using the DS64s for routing via a throttle, especially in a hidden staging yard.
