Is there a specific problem on your layout that just won’t go away, no matter how much you try to be rid of it, and you’ve tried everything you know?
I’ve got a problem like that. A piece of my mainline keeps pulling itself up to the point where I’m afraid to run anything through it. I’ve added track nails and removed surrounding scenery to try adding more Liquid Nails to the trouble some spot. I am just considering removing the section entirely and turning it into a scene in which a track gang is working on the mainline.
I wonder if that piece of mainline track is under pressure from both sides and that cutting a gap or two in the rails might help more than nails and glue.
Failing that, you don’t say your scale or what code rail you use but a white flag you could wave rather than the total surrender of just making it an non operaating part of the layout, would be to use one of the commercial integral track systems (where the roadbed is cast integral to the ties and rails) in that area alone. Kato for example. In the old days using the Tru Scale integral roadbed and track would also be an option.
And this may sound truly insane but there is also the old “Lionel track” trick: a few carefully placed twist ties that bind ties down into holes in the benchwork and are fastened below.
Okay so I would definitely try what Dave suggests. Sounds like you have a pinch point. Nails won’t help you with blue foam. After you cut the gap, add your adhesive and then put something very heavy on the track to hold it down while your glue sets up.
LOL! Yeah, we’ve all got them. I have a turnout/frog that causes a loco to hiccup every now and again. It’s not always the same loco and the turnouts/frogs before and after don’t give the locos any problems. It’s not a huge/high priority fix, but it’s one of those annoying little hiccups. What’s even funnier, I have feeders at all joints of the turnout and it still hiccups.
Like others have said, sounds like the track is bound/under pressure/kinked from somewhere and that is the weak point where it shows itself. I had one of those and a little relief cut fixed it.
Isn’t model railroading a series of never ending problems, along with a few moments of enjoyable bliss? interrupted by peaceful lone moments that make the rest of the world disappear while we enjoy ourselves.
my N scale code 80 switches, and a short 9 3/4 piece by a switch which causes derailments to 6 axle diesels and steam. then the straight piece on the other side of the switch is set funny so my trains essentially go over a bump.
