Is there any justification for adding (soldering) a rail ground wire to a K track right or left hand switch or crossover. It seems that this is one area that could use a ground to increase digital reliability.
Also does it make sense to alternate the ground wire on either side of the K track vs. only one side?
Does it seem the Marklin reed switches are too big? They sometimes interfere with the center stud power. Any solutions out there?

On many pieces of track there is no connection between the left and the right rail, so it makes perfect sense to feed both rails.

Yes.

I ensure that every 'chunk' (up to about 2m each) of K-track I install has the following:

  • Each piece of rail has the underside (red pole) soldered to the next track. The copper contacts are easily soldered together and it makes a nice rigid join.
  • Each chunk has a red wire soldered to the one of the joints on the underside.
  • Both sides of the running rails at all joints have their rail joiners crimped after being connected.
  • Both sides of the running rails have a ground wire soldered to a rail joiner between every isolated section.


The 'chunks' can then be placed on the layout and joined to the next 'chunk' without worrying about electrical connectivity between the chunks. This makes laying the track manageable and produces an extremely reliable system.

Do it all right, once, the first time, and you won't have conductivity issues.
