My entire (moderate size) layout is Gargraves including 19 switches. All new. I think they made a change to the way the switches are powered some 10-15 years ago. There not powered through anymore which is safer.
Yes - the post above is correct, they are a pain to solder, but can be soldered. I elected to use the pigtails. They work great and no need to solder. The curves, straights, and flex track work well and look good weathered. If I had to do it again would have used Ross switches. The other minor issue is the small gaps between the track joints. Adds noise and are sometimes sharp and need filed. This was fixed with conductive epoxy filler. Worked great. Just a suggestion but you don't have to use screws or nails. Just glue down with Titebond II. Very quiet and strong.
