I'm moving to Spain next year, and after many years of having my Hornby Dublo collection packed away, with just the locomotives in a wall cabinet, I'm finally going to have a dedicated railway room in the basement of our new villa
I have a fairly large collection (most of what they produced, with only a couple of locomotives still to get), and intend to build a combined 3-rail and 2-rail layout to display it all.
It's nearly twenty years since my last combined layout, and at that time I used Peco flexible track on foam underlay for the 2-rail, which gave a height very similar to the 3-rail metal track, so it looked good running side by side through stations etc, and enabled me to have a four-track main line using the two fixed radii of the 3-rail on the inside and the flexible Peco on the outside two tracks. Obviously the hobby has moved on, so what track would be suitable now for the fairly coarse flanges on the old Dublo wheels, and would connect easily to the small quantity of old Dublo 2-rail that I still have? (On the old layout I used new Peco for all the high speed sections, including new Peco points, and the old Hornby track for sidings, so am planning to do similar this time). Also, what would be recommended to get the height of the track to match the 3-rail (foam underlay, cork??), as the old foam underlay disintegrated after a few years use - has it improved?
