Investigations have shown that horizontal, and vertical components of acceleration occur as a result of unevenness of a rail line. A rail line must be considered along with centrifugal force if a smooth ride is to be achieved. The Murmansk section of railroad, has more than 50 percent, and in some cases, 70 percent of the curves with radii between 230 and 700 meters, and the intervals between curves are short. This article gives Shperling's formula for calculating a smoothness factor, and shows some of the curves which are recorded. Also included are suggestions of changes that should be made in maintenance standards needed to improve track conditions at curves. Graphs are provided which show Shperling's curve for smoothing factor calculation, and data taped by the track geometry measuring car for curves of 625 and 714 meters in radii.
