don't sell them keep them, I must admit to having a collection of 3 rail myself and I'm constantly thinking about a layout, I have even a plan for installing a picture rail in the living room, which obviously will have a circuit running around it.
I have a thing for Duchess locomotives so I have in the past bought a few rough versions to re-build/restore I nearly have as many as the LMS had, just need to get enough time now to pass them through the workshops
