We have a 3000 Sqft layout at the club with soldering only inside control panels, turnout motor pigtails and track drops.
All buss wires connect to terminal strips between each table, with local power branching off with spade logs stacked on the terminal strips.
Track drops go to terminal strips within 6 inches, then fed to control panels with crimped spade lugs.
When we had some track drops backward and miss labeled, swapping connections took less than 1 minutes to unscrew and move wires. And no solder drippings either.
More options are available than melting metal.
