Need help with old O11 & O12 switch wiring

Thanks. Yeah I need to learn how they are built and what they need.
Photos of the findings is a good idea.
Anybody have experience with these in a layout?

I don't believe the 012 are non-derailing, but the 011's are. The coils take a large amount of power to operate, even when properly lubed. The non derailing function works marginal at best, even if you modify them for fixed power. If you try to use the non-derailing feature to consistently operate the switches in a fashion for a double reverse loop layout, you will forever be re-railing trains after they derail. If you want to do that, I highly suggest fastrack switches for that purpose The circuit in them is much more sensitive to detecting trains and much more reliable.

Was there a special reason for retaining the old switches to maintain the character of the layout? If you're staying with conventional track, the 022 switches are a better choice.

Amen to using O22 or Fastrack  switches.  De-railments are frequent with the O11 switches.  There is two much of a gap at the frog for many lead trucks to bridge, thus de-railments occur. The metal used on those switches wore easily and though the non-derailing feature of the O11s was great, they were not reliable, especially when some of the lighter pre-war locomotives, ie 259E  and those of that type were in operation.  In the posted photos, the gap at the frog is clearly evident.  

The gap is TOO much, not two much.  Sorry.
