Hi Berkshire. Sorry to hear of your broken spring accident. I am under the impression that MARX Manufactured 027 tin track curved elevated long ago. I have only seen this with a couple of boxed sets. If Marx did not make these it's a mystery that toy train historians might share. Perhaps some forum member can assist you with a useful link. I would experiment with the the height and safety of travel. I did this in my last layout with 031 curves. Super elevated with a 36 inch piece of O Gage cork roadbed placed just under the outside curved rail, then the track fastened down upon his it. You can use other Gage ( H.O. or S) cork and experiment. I have used popsicle sticks to experiment in the past. Once figured out what your height requirement is, you can use other materials more along the Prewar feel. Should you try this, remember to have at least a lead track supported with slightly less height than the curve so that your engine doesn't jerk into the curve. Do you have a photo or video of your set up where the accident happened out . Don't run the risk of the curve being twisted abruptly. In other words gradual elevation is helpful. How sharp are your curved tracks?
I ran post war equipment at desired thrilling speeds with the track right on the edge of my three door wide door. Not only worked flawlessly, without worry, it look great with trains on a slanted curve. A little slant goes a long way. Lol.
Not sure my response helped. I know for myself I never had an engine go over the edge on my tight banked curves.
looking forward to your posts and others on this matter. Best of luck to you.
leroof.
