I recently purchased an old Casadio 3-Way Remote Turnout and was wondering how to wire up the controls. It appears to be two separate remote controls, so I guess that I could hook up two different switch control boxes, but I this would then require syncronization, since two controllers mean four possible states, and the turnout only has three states (left, center, right).
Is there anyway to wire this turnout using one switch that would allow me to choose, left, center, or right?
A 3-way turnout is really just 2 ordinary turnouts mounted on the same base. The first set of points either puts you on a single track or on the path to the other turnout. The second set of points selects between the remaining 2 tracks. There aren’t 4 states, because one of them is a “don’t care” condition when the first set of points selects the single track.
Wire this as 2 separate turnouts. That’s the easy way to go.
You could look into using a “diode matrix” to select the path. For a single 3-way turnout, though, this is really overkill unless you really like this kind of thing.
If I understand this correctly you could achieve the same sort of thing with a standard left or right hand turnout and a wye or even another turnout used in sequence. I would be tempted to use two switches as well. I assume the switch uses twin coils? If so I would use a couple of ON-OFF-ON momentary toggle switches to simplify the controls.
If you wanted to take it a step further…if when switching the initial diverging turnout you wanted a default setting for the second turnout you could devise a circuit using relays etc. so that throwing the first turnout would set the default diversion for the second turnout, (it would have to be momentary power if twin coil) unless you choose the alternate diveging route. Or something like that…[:)]
