I decided to move a couple of Kadee delayed uncoupling magnets from above the tracks, so they were out of sight below the tracks - not so easy to do after ballasting.
Before
First I removed the rails with a Dremel and cutting disc. I did this carefully as I wanted to use the rail again.
I used the magnet’s base plate as a template to cut into the cork and baseboard to the correct depth.
I relaid some new ties with the original rails which were the right length. I also cut some fishplate joiners in half to slide across the rail join.
Finally I re-ballasted the track in place. When the glue is dry I will repaint the area
Thanks George. They are in fact Kadee undertrack uncoupler magnets but appear identical to Bachmann’s in every way - except for the ‘little plastic bloke (LPB)’ you get with the Bachmann version.
I myself like them and tend to mark their position with a short length of rail painted yellow, sticking out of the ground.
To get round unwanted uncoupling I limit their use to the yards, easy for me as the whole layout is a yard. I also over-weight my cabooses to create some pull on the knuckles within the train, thus reducing the potential for unwanted uncoupling.
