A new Scale Speed Calculator is available on this website for everyone to use. Just enter the distance the train travels (in inches), the time it takes to travel that distance (in seconds) and the scale you would like to convert to and click the calculate button. The scale speed will be displayed below the calculate button. If there are any modifications or changes you would like to suggest for this new feature, please let us know (admin@harm-web.org). This new feature can be found on our Resources page or by following this link (https://www.harm-web.org/scale-speed).
