Does any company make 27 and 30 inch radius curves?

Flex track is your best option for the curves you ask about. Easement refers to a curve of decreasing radius leading into the actual curve radius you are trying to create. The raising of the outside rail in a curve is called superelevation. Superelevation is actually a banking of the track to offset the lateral forces of the train in a curve. Like on a race track (well, kind of like), it allows the prototype to negotiate curves at higher speeds. We do not generate these lateral forces on our model railroads, so superelevation is purely cosmetic. If it is overdone on the layout, you can pull your train off the track on the inside of a superelevated curve. Done in moderation, superelevation and easements add a lot to the appearance of your layout. <br /> <br />Tom
