MTH Track question on connectivity

Hi

Water and electrics don't go well, you probably have created a bad contact due to water damage

If you have a voltmeter or can borrow one just run it over the bad piece of track and you will see when it fails, most likely its the center rail. When you find the bad joint you will probably have to replace that section of track or solder the contacts to make good

You could also use a lighted piece of rolling stock and you'll find the problem quickly when the light goes out.

Thanks for the ideas guys!!

I recently brought out some old MTH track and was having some problems, the copper hooks on the bottom weren't touching enough, one was curled away too much.  So I took a screwdriver and straightened it out to provide a better connection.

Two possibilities:

You may find a badly oxidized center rail copper contact on the track where it is stalling. It might be easier to replace that track, but the contact can be cleaned using DeoxIT DN-5 or another plastic-safe contact cleaner.

If that is a wood base below the tracks, the platform may have warped, or expanded and the contracted, causing stress on the contact point. That might require more work (replacing the base), but you might still be able to salvage what’s there by adding a jumper wire to the broken contact area.

Lift the dead section of track and blow dry underneath it. Also blow dry the copper contacts.

Also, if all of the track got soaked, you may find other oxidation problems at other joints eventually.
