Re: Power source for turntable motor
DanielW <danielwatkins1953@...>
It's the Walther 90' Built up Cornerstone series, model #233-2840. This is the fairly expensive turntable, not the cheap build it yourself one. One set of leads are brought out for the track power and another for providing power to the motor. The controller has positioning capabilities for programming up to 60 stopping spots. It will accept either AC or DC. I'm not locked in to using resistors, just what the tech person at Walther suggested.

I just want to be able to reduce the voltage output from my transformer to a usable safe level for the turntable motor. I'm open to all ideas. Thanks, Dan

Re: Power source for turntable motor
Vollrath, Don <dvollrath@...>
We need to know much more about the turntable. What make and model? Does it have electronics for positioning inside or are the motor leads brought out directly? What does the turntable installation data sheet say about it? Will it accept AC or DC? Usually adding resistors isn't the right method. [Works for light bulbs, but not motors or electronic controls.] I ended up using a 5V voltage regulator on my TT motor to control the speed.

Re: Crazy Eight that Double Slips
Vollrath, Don <dvollrath@...>
There is the equivalent of a wye where each of the center legs of the figure 8 merge into the outer loop. Isolate the straight portions of the outer loop parts of the wye. Both of them. Turn those tracks into 2 A-R controlled reversing tracks. The whole figure 8 including the double slip crossover can be all the same fixed polarity.

We went KIS. We replaced the whole works with a reverse loop and handle yard/staging on an entirely separate module. This was easier to wire and maintain, and got rid of all the weird corner case anomalies. We thought about trying to create a smaller section under PSX-AR control and having the rest under a specific phase. We opted out of this because we kept finding ways to short the PSX-AR section if the section were shorter than our "longest train". -John

Re: Reverser Yard
Vollrath, Don <dvollrath@...>
There is another way that doesn't need an auto-reversing unit for tracks in the yards. 1) Isolate the entire double crossover using 8 insulated rail joiners, and power it through a PSX-AR. 2) Use a DPDT relay to select track polarity of the two yards to be a) same as the track feeder from the main on that side , OR b) same as the feeder from the opposite side main track. 3) wire the relay coil to operate only when the crossover turnouts are set to X-over. Now the yard tracks will still match the polarity of the selected yard leader, but the PSX-AR won't carry or be be affected by power drain in the yard tracks.

The only thing you might ned to do is to make sure that the PSX-AR is adjusted to give reliable reversing detection AND not keep flipping the polarity once it is triggered. For that you may need to make sure the DCC feed can supply all the peak current needed and if necessary possibly rework some of your power hungry sound powered locos to minimize inrush current. DonV

"Thanks Don, You are confirming what I thought.

Don is absolutely correct - a second train will not cause the PSX-AR to malfunction. It would be interesting to have your friend lay out exactly what he thinks will happen to the PSA-AR when it detects the short from a train entering the reversing section and reverses power to the reversing section. Once we know what he thinks is happening, we can help him understand why it is not an issue. Best regards, Steve Haas Sammamish, WA

Re: Reverser Yard
Vollrath, Don <dvollrath@...>
Mike, re-read my previous answer. The couble crossover completes a wye that attaches to the mainline in two different directions. There is the reversing problem. As long as you vow to never have two trains traversing in/out of left and right yards at the same time (even though it is possible if you set the double crossover to 'straight')... Simply isolate both legs toward the main and make the double crossover and all yard stubs into one giant reversing section. Throw all 4 turnouts of the double crossover at the same time and almost any purchased crossover will not have any issues with that. Doesn't make any difference at all how long the yard tracks are, as long as they are not somehow connected back to the main line at the far end. Trains inside the reversing section will not be affected by A-R polarity reversals.

The pink slashes represent the locations of the insulated joiners that create the reversing sections. The yard tracks could be as much as 24 ft long. You cannot get from one reversing section to the other, only from the yard leads. While it is not physically impossible for two trains to be entering the reversing section at the same time, they will have a collision before a short occurs. Again, my concern is whether I am going to have a problem because there may be trains operating totally inside the reversing section while a train is entering or exiting the reversing section tripping the reverser.

Re: locomotive hestitates but restarts if i throttle down
Robert T. White
Is the spot where it is stopping between two power districts or a long way from the booster? Have you checked your track voltage, current, and signal strength at the spot? If the above are good and this is the only loco experiencing the problem, I would try another decoder and see if the problem persists.
