oldpa posted:So what I need to know is, do any of the O27 Lionel switches have a constant power connection or which is the best one to modify and how is that done. This will be used for a reversing loop.
I have read K-line made a good switch w/ constant power, in fact I posted in the” wanted to buy section” looking for the K-line.
Yes, the K-line 027 "low profile" switches are the best bet IMO because they function similar to regular 0-gauge 022 switches, if you can find them....
NOT THESE;
but THESE are better;because the don't "buzz" and overheat if a train parks on them.
note: photos show manual switches but they come in remote as well......just sayin'.....
