Switch Machines Pt. 3 …

Since I have the switch machines installed, wired up and programmed I thought I was set. Using my new found power to throw switches on demand, I was feeling pretty good about all the crawling around underneath the layout hooking them up. Went to grab another local freight from the staging yard and found I had a problem.

Digitrax’s (digitrax.com) DT throttles are full function. Their UT (utility) throttles are not. Which means that an operator, usually the yard operators, are unable to throw a switch from their throttles. Not  wanting to scrap the UT throttles and replace them with DTs (hello, they are expensive) I was going to have to do something.

Turns out that “something” isn’t that difficult.

My plan has been to use the fascia as a “kind of” control panel. Like I had done  with the staging yard, the towns will be laid out with striping tape. White for the main lines and the sidings in yellow. Industries will have their names and car capacities labeled. The number for the switches would also be by the turnout. Also kicked around adding LEDs for turnout indication.

The plan was to do this as time permitted. But the need for a way to control the turnouts locally moved the project front and center. In addition to the above I added a momentary push button switch to the panel at each turnout location. The DS 64s have additional input capabilities for just this situation.

Of coarse this meant pulling more wires. but one does what needs to be done. And actually with the roll around wire rack this really isn’t work, just time consuming.

The solution in pictures:

Fascia with industry labeled. Track capacity number is also on the fascia.
Fascia with the switch numbers in place. Holes for push buttons and LED indicators.
Fascia going in place, push buttons and LEDs installed.
Fascia in place.

Don’t have a shot of them lit up (the LEDS, not me), but I will try and get one for the future. The LEDs are powered through the DS 64 and the red (for a thrown turnout) is not as bright as I would like, but the green is. And when you are rolling through town with a hot freight green is what you’re looking for. If I wanted to as a future project, I could rewire the LEDs through the extra contact points on the switch machines, but for right now they are fine.

So Jackson has it’s switch machines in place with control from either the throttle or the fascia. For right now its a lot of fun switching the town, though I’m sure that it wear off after a bit. Which is a bit sad.

For now that’s it, next time we switch gears again. Till then Happy Modelling…

 

 

 

Switch Machines Pt. 2…

Having installed the switch machines, it was now time to add power and control. As I had mentioned before, on the last layout I only used the DCC system for locomotive control. When I started  this layout I was determined to use more of is capabilities.  That means the switch machines will be controlled from the throttles as you walk around.

So to do that meant the installation of Digitrax’s (digitrax.com) DS 64 stationary decoders. Not a big deal, as I was collecting switch machines I was also collecting DS 64s. They are mounted in the electrical cabinet (if it’s electronic , it’s in the electrical cabinets), the initial question was how. If I mounted them on the back or side wall, access for wiring, programming and maintenance would be a hassle.

The solution (and my original plan that I wasn’t sure would work) was slide out panels. That way I could pull the panel out and sit in the aisle to wire or whatever.

I cut the panels  (I made two) to size. Using templates of the DS 64s I laid out placement. Then added in where the wire runs would be and added in cable holders.

Panel for the switch stationary decoders ready for the DS 64’s. All mounting holes for the decoders and wiring looms are drilled, with the decoders numbered for switches controlled.

I then mounted the DS 64s and the wire looms and they were ready to slide into place.

First set of DS 64’s mounted on panel and ready for the layout.

Once in place it was a matter of pulling the wires and then the long process of hooking them up.

DS 64’s mounted and panels slid into place.
The DS 64’s mounted with the wires pulled and ready to be hooked up.
First set of DS 64’s in and wired, ready to be powered up and programmed.

With that done it was it was time to start programming the decoders. I had watched the video from Digitrax several times. Though it looked straight forward, I figured that meant that it wasn’t. Turns out it actually is as simple as Digitrax says it is.  With the switch motors wired and programmed I went around to make sure they all worked properly. A couple of them were working opposite of what they were supposed to be doing. It was a simple matter of reversing the wires to set that straight.

Now, you would think that this was the end of this story. Turns out there is more.

Next time the saga continues, till then… Happy Modeling…
