Jerry, there is an excellent write-up by Don V in the Files area under ‘SW Machine Controls’ called ‘SLO-MOS.doc’. Look at Figure 1.
That shows how to wire two or more switches for multi-point control. However that uses DPDT switches.
I can’t think of any way to do it with SPDT switches.

Subject: [WiringForDCC] Dual Turnout Control
The subject line might be worded incorrectly, but what I am looking for is a circuit that will allow stall motor turnout machines (Tortoise) to be thrown at the site of the turnout and remotely as needed. Will I need a second switch at each turnout to lock out the local control? We are using the SPDT, three-wire option for local control described by Circuitron for the Tortoise machines.
