Reply to "The best gauge of wire to use ?"

I’m an MTH/ Gargraves track guy. 

The lockons for MTH are simple. 

You can add them on any track section with out having to dismantle the track.

From the pictures, it seems you need to commit to every section, “just in case”. To avoid the need for track dismantling. 

Since I run in power blocks, I would commit to a connection point every 10-15’. 

And use the female blade terminal like Tedw is doing. 

Because the track to track connections on Lionel look sufficient, mechanically speaking. 

Not much else will make that system easier to utilize.
