I think that is what is happening. It's more frequent on the turn that is slightly pitched. I put a shim under the track and that helped out. The plywood sitting atop the pool table is a bit warped but I'm not ready to take the layout apart just yet for a more permanent fix.
As to my other question, when this happens is there a risk of damaging anything in the engine? I'm reminded of the saying where there's a spark there's a fire and in the short run I don't want to risk wrecking anything. I could just put the engine on the shelf until we build a more stable layout. Apologies if the question seems to fundamental, but new to all of this.
