[quote]QUOTE: <i>Originally posted by wenjclute</i> <br /><br />I'm doing my first ever lay out. It will be HO scale and I have a some questions. what is the distance between roadbed that are on a straight line. Also the distance on 22", 18", and 15" raduis between road beds. I may have to use a 15" raduis ,180 deg. on the main line. What sort of problems might I have. <br />[/quote] <br /> <br />For HO scale, plan on a minimum of 2" on center between parallel straight tracks. For curves you have to add more. How much you add depends on the length of cars and locomotives you plan on running. You need enough seperation to keep the inside and outside trains from clipping each other. For a 28" curve I planned on 2 1/2" on center seperation. <br /> <br />I'd definately steer away from that 15" radious curve in HO. Most manufactureres will give you a big thumbs down on that one. Short cars will track it, but most locomotives of any kind will complain or derail. 18" minimum, and MUCH bigger preferred. Stick to a 22" minimum radius for reliable operation if you can. Also remember that stuff will looks screwy running on a sharp turn. Once you can see the outside rail under a car or locomotive, then all realism goes away. <br /> <br />Mark in Utah
