Anyone at all?

Lionel Fastrack  power supply and plugs has a 5.5mm OD x 2.5mm ID https://ogrforum.com/...c/129252226560423354

Ben,

1.) Vernon also gave us a more detailed hint in a posting about three weeks ago.  This photo from his post describes the size of the plug:

2.) You just need a socket that this will plug into, with a couple of pigtail wires coming off of it to connect to the power tabs found under your Fastrack section:

Here's one option, from Amazon, which requires soldering:

There are others that don't require soldering as well.

3.) And finally Lionel 6-12053 to go between the socket and the track:

Thank you! I might try the one from Amazon which requires soldering. Question: is this polarity sensitive, or can I wire either rail to either part of the plug?

I would follow the convention, center pin to center rail, outer to outer rail. That way additional power drops using fastrack OEM components would match.

Edit: FWIW, most Lionel locos won't care about polarity as they run on AC or DC. This is mostly just to ensure compatibility since you are using fastrack and DC supplied adapters as your power system and in general, just best to follow a convention.

Another option; Lionel made O-36 curved LC terminal tracks which were included in the Lionel Junction sets...they are out there!
