Just back from a pleasant visit to Gardiner The Train Doctor, home of Gargraves track. The family that runs business and all of the employees I have met are died in the wool toy train nuts. I noticed hanging on the wall some curved sections made with real wood ties. When I inquired about it they said they have been producing it for about six weeks. It looks like they have taken their bendable track and formed it in a jig. The section is held in place with a pair of metal bands tightly fit in slots milled into the underside of the ties. Ballasting should cover up these bands.
When I get the layout built I’ll probably just use the bendable stuff all around but for temporary holiday layouts this looks like the way to go.
