John, I was assuming you would run the smoke unit from track voltage as it is now. If you run it from the R2LC it might smoke like a Lionel:-)
Yes, you have plenty of options. Run from track modified with a circuit to puff with Chuff.
Run from R2LC so you can turn it on and off and reduce the volume.
Run if from Track voltage via a relay controlled by the R2LC, so you still can turn it on and off.
Integrate the REG Board Lionel uses.
For the reed switch, you could mount it on the tender and run the signal in via a harness, which you may have to have anyway.
Not sure what the insides look like, but my J has plenty of room and a smaller than the motor Flywheel. A magnet or a trigger could be attached to the fly wheel and trigger a chuff switch or reed that way. That would also allow for more than one chuff on the reed switch.
What program is used to draw the circuit diagrams? Is it a free application?
The one element is on at 8Volts and the second comes on at 10-12 volts. G
