Atlas Remote switch machines

[JRP]

Has anyone used DCC to operate remote switch machines made by Atlas? 

If you're not familiar with them, they are the Atlas device that, when wired to your accessories power, will change the direction of your turnout by first manually sliding a button either right or left and then, by quickly pushing this same button down, activates it.  If you hold the button down longer than 2 seconds, Atlas says you risk blowing out the switch board. 

I was wondering if my DCC system could accomplish this same operation but without having to manually push the button or even slide the button to either side.

I haven't used DCC for powering mine, but it will work.  You can do this in parallel with the control-panel switches, or just use DCC and forget the control panel.  You'll need a "stationary decoder" module for the DCC connection.

Those Atlas pushbuttons don't have a good reputation.  They have been known to "stick" in the closed position.  Even though you might not intend to hold them down for more than the recommended two seconds, they sometimes do this all by themselves.  This teaches you the distinctive smell of a fried Atlas turnout motor.  Instead, many people use simple single-pole, double-throw momentary contact toggle switches.

I operate many of my Atlas twin-coil switch machines from my DCC throttles.  They work much better, and more safely than with the Atlas push buttons.

I use Lenz LS150 decoders for the switch machines.  Each LS150 will operate six (6) turnouts.  Cost is about $45 per LS150.  Plus, you need an AC transformer to supply power (16V max.).  I had an old Atlas Generator (from their DCC system) and it works well.  You could also use the AC output from a DC powerpack.  Only one AC power supply is needed for as many LS150s that you want to use.  I'm using four of them.

This gets a little expensive but is well worth it if you like to operate the turnouts from your throttle.  One note of caution which may not apply to you.  I have a Lenz DCC system and tried a CVP radio throttle with my system.  When using the radio throttle I would get that continuous buzz and burn out the motor unless I just tapped the throttle keys very, very quickly and lightly.  Then it worked fine.  But with all my other Lenz throttles, including the cordless phone throttle, the turnouts throw nicely.
