Hi All!
Hope you all are doing well, I've had a extremely busy week or so.
One of the switches I have seems to be operating just fine with the exception of the train losing power as it crosses over the switch.
I presume the middle rail must have a connection loose or missing, but I've not yet been able to pull it apart.
Any ideas?

Usually it is a solder joint inside the unit. Flip it over, remove the screws. Look very closely at all the joints. They may look soldered but are actually lose.
There have been many maintenance articles on the 022 turnout. Do a search.

Spice7 is right. Most of the 022s I picked up used needed to have at least one joint resoldered. There is one in particular that seems to be prone to coming apart.

Thanks guys makes sense!
The other one in the pair a joint needed to be resoldered that controlled the anti derail feature.

I went to harbor freight today and bought a cheap multimeter. I've decided that the problem is not a soldering joint, but that the middle rail over the switch point is corroded.
When I run one of the probes of the multimeter to test for continuity the meter generally does not prove any continuity except for at the center point where the rivet attaches the center rail section to the switch body.
However if I take that probe and push it hard against the middle rail at any point it will always show continuity.
I tried using the back side of a kitchen sponge, and that seems to have helped a little bit, as the multimeter shows more continuity.
Is there a solvent that will help but not melt the plastic? Or could I spread some solder across the rail?
