Theo, yeah, this project really got me going too. Can't recall their name but a member here is in a woodworking club and they do an annual project this might be perfect for. Could be made mostly from cabinet shop donated scraps, quick, simple production line parts, and someone could make the engines and cars, buying wheels in bulk. Really appeals to me.Tom I really like those designs. They would work very nicely on a model train layout, or at least 'I' think they would. And that link gives me some inspiration for a layout. I'm not going to make train tracks, so won't need the bits, and I'll pretty much design everything else myself. Almost makes me want someone I could make one for. Almost.
