There's a possibility that the track is on the wrong layer as well. If you are using layers, ensure you are on the route-layer always while editing and use the other layers for special case items such as scenery assets. Infrastructure assets such as track, bridges, trackside objects (signals and their ilk), need to be on the route-layer.
If these assets are on the wrong layer, you need to move them to route layer. There is a way to do this in Bulk update-replace-delete utility, but I don't remember the details. The easiest way is to merge the secondary layer into the route layer.
If you edited in the Session instead of the Route equivalent of Surveyor, you will need to move the assets to the route layer there. In both cases, I recommend making a backup of the route and session first prior to this operation. You can use Content Manager and export these assets to a CDP for safe-keeping.
The track is older Jointed Rail JR US #132 lb. track, or something like that. I've used that often as well as the rusty versions and I have customized the track-quality to make really, really rough track for sidings as well as changed textures to make really, really, rough rusty dirty track.
