Hi,Andy Tait submitted a full set of schematics that illustrate how to wire a double crossover using four Tortoise switch machines. I may be the old fashion type, but one way to set controls in a panel is with push buttons and a power capacitor supply. Hi all!I am about to wire all turnouts and the big issue is the double crossover (with live frogs) whose ends have 4 double slips.
Thank you!I actually suspected the frog juicers could not be used in analog mode: therefeore I will make the double crossover only DCC-friendly and all non-analog engines will avoid it. Hello Kurt,Although it's not prototypical to control a double crossover manually it's technically feasible with the BullFrog switch machines using 2 micro switches mounted on each of them. Mounting Circuitron's Tortoise switch machines on my new layout's 2"-thick extruded-foam insulation baseboard has been challenging. I will be using a series of 4 pole, 3 throw rotary switches and probably a handfull of diodes.


All turnouts in the layout (Tillig and Weller) have live frogs.As I am planning to use small servo motors to shift the point blades, this is my question:should the servo motors directly be connected to a digital decoder (such as Uhlembrock's or ESU's, for instance) that does not provide any polarity and then should the polarity of the 6 frogs be provided by 1 big frog juicer?
Simply replicate the wiring for the Tortoise machines that use contacts 2 through 7 and orient them the same way on the micro switches, where one switch would be contacts 2, 3 and 4 while the other is 5, 6 and 7. Although individual Tortoise contacts are break-before-make, there is no assurance that two different ones will obey that sequence.
I tried the hook-and-loop fastener solution explained in the October 2005 Model Railroader but didn't like the wobble or the actuating wire's long reach through the foam board. There is a chance that a dead short will occur through the Tortoise contacts, even if they are thrown at the same time. After some experimentation, I've developed the mounting method that's shown in the illustration. I do not know what would be simple or difficult for you, so I may not be able to give the best answer.


Wouldn'it?And it seems to me this scheme is fully valid for DCC operations (I would like my layout to be DCC-ready) but not for analog ones.Unfortunately, as I still have some locomotives without decoder, how can I feed the frogs in analog mode?I know for sure that, in order to avoid troubles, all analog locomotives will not be allowed to enter the double crossover (DCC operated) but at least, I would like them to go through the double slips.What happens to the frogs in analog mode?
This will lead to an early death of the contacts.My updated schematic avoids this issue with a minor change. I am also untested at creating drawn images as shown above, so I would also be unable to give even the simplest of schematics. I did not update the animated versions, just the master.Also, if anyone wants it I will post my control wiring diagram. It used two DPDT switches; one selects normal or crossover, the second selects which way the crossover goes when the first switch selects crossover.
