Hey everyone! I'm new to the forum and new to model railroading - I posted an introduction if you're interested in knowing what brings me to model railroading. Anyway, for my first Z Scale layout, I want to go small so I can be encouraged as I see progress. I've employed some of my tools in the garage and put together a 2' x 1.5' foot box which can set on top of a table. This fits the standard Z Scale oval of track. While I have a fair bit of original Marklin track, laying the cork roadbed and then ballasting seems a daunting task to me as I've already seen how finnicky Z track and trains can be. I glued a small section of track down on cork elsewhere as an experiment and had to carefully file a few places and it was just not a pleasant experience. My father-in-law is into model railroading and suggested the Micro-Trains Micro-Track with built-in roadbed and ballast. So I got the basic oval and set it up. Here's the thing - when the oval is completely snapped together, even if I have it caulked down and flat, my Marklin 8827 engine partially derails. Either the front wheels will pop off the rails, or the second set of wheels from the front, messing up the electric pickup. It looks like the train "hops" up at a few places where the rails are joined together. I tried filing these joints more level with each other, but it still happens! I have a suspicion that the metal rail joiner itself is push up the train's wheels. When I had been using the Marklin track, I didn't see this kind of thing happening. Are the Micro-Trains sections of track shallower than the Marklin track or something, which could cause hopping like this? Do any of you have any advice / tips? Thanks!
