Im having problems with my Auto Reverser can any give me some tips its just on a why setup i did what told me on the phone and look at there pdf file i hope some can help get it outing or in the trash it will go its just a wast of money help please tom
Can you be more specific about the issues you are having? The PSX-AR is an excellent auto reverser. But you have provided little information on where your issues are. What DCC system are you using? Can you show us a track diagramand how you connected AR? Are the rails on the reversing section fully isolated from the normal sections of track? Can trains bridge both ends of the reversing section at the same time?
Ahhh... a WYE, not why! I had to read twice. So it sounds like you want to know where to put the insulators. Generally where the wye leaves the mainline you put insulators, both places that leave the mainline. This assumes that it really is a simple wye, with a "tail" that does not connect to anything else. The longer you make the reversing section, the better as a simple tip. Greg
I don't want to hijack the thread, but while we're on the topic of DCC and reverse loops, my smallish new one-man N Scale railroad will be primarily DC (because I've been in N for a very long time), but I will be providing a master toggle switch to instead select DCC to power the railroad when I venture there someday. My road will have a manually operated reverse loop, which presents no mystery to me in DC. It will be traversed only one time per operating session, so automation isn't needed. DCC reverse loops are a mystery to me. I read on [ https://www.thesprucecrafts.com/reverse-loops-model-trains-2382604 ] that "reverse sections can still have their polarity flipped manually with a toggle switch with DCC. The only difference is you will not need to change the direction switch on the cab as the polarity in the rails no longer determines the direction of travel". Is this true? If so, I think I can figure out a reverse loop circuit to handle both DC and DCC. Thanks for any thoughts you may have.
Indeed with dcc, eg if a loco is commanded to drive forwards, it makes no difference on the polarity of the track - and even if the polarity is then switched, the loco will continue in the same direction.
Yes, very true. Track polarity is irrelevant to direction of travel; but very relevant to avoiding buss shorts.
Thanks y'all. If I understand properly, with DCC all I have to do is wait until the train is within the insulated portion of loop and then move the toggle switch to reverse the insulated section's polarity and the train will happily exit?
Depending on the complexity of your layout, it may be preferable to have the toggle switch reverse the polarity of the track outside the insulated section. This way, when using DC, it is not necessary to change the direction of travel of the locomotive when it is inside the insulated section. Robert Pearce (aka ViperBugloss)
I model (more correctly "play trains") in Z Scale. I tried this idea out a few years using Rokuhan track on my dining room table. I always think that this a good way of trying ideas out, however I appreciate that this is not always possible. This thread has rather gone away from the original question about using an auto reverser on a Wye, but the same idea applies. If possible, build a little test layout and try to isolate the problem in this way. Once the concept is understood then incorporate it into a larger layout.
That's sound advice Robert and testing is rather fun. I'm not an Electrical Engineer, but I really enjoy messing with electronics. My layout room floor is a jumbled mess of power supplies, jumper wires, LEDs, toggle switches, resistors, meters and notepads. I just read that DCC track power is square wave AC, which is interesting. I need to educate myself on the basics of DCC.
