Curves just as with real railroads, there are several factors that have to be considered in laying out curves: minimum radius, spiral curves, superelevation, and s-curves. If prototypical radii were used for a model railroad, the space required would be tremendous.

• improvement of railroad track inspections and overall railroad management due to the much greater use of table formats for clarity and understanding. • improved inspections since the ufc now differentiates between railroad maintenance requirements and the very minimal fra safety standards.
Field engineering guides had tables for curves from one half to 30 degrees. If they were plotting, say, a 10 degree curve, they would deviate from straight ahead half of that to the side, measure out 100 feet in that direction and mark a point. Then they would lay the track so it would be centered on that point.

The minimum railway curve radius is the shortest allowable design radius for the centerline of railway tracks under a particular set of conditions. It has an important bearing on construction costs and operating costs and, in combination with superelevation (difference in elevation of the two rails) in the case of train tracks, determines the maximum safe speed of a curve.

Railroad curvature inhibits a driver’s view down the tracks from both a stopped position at the crossing and on the approach to the crossing. Crossings located on both highway and railroad curves present maintenance problems and poor rideability for highway traffic due to conflicting superelevations.

Railroad spirals do not hold to the length rule so their needs to be some interpolation of the tables to achieve a reasonable solution. Use the tables to determine the long tangent and short tangent for a 390 foot spiral. Use the data for a 2d 00’ curve or interpolate if the variation is large enough to make a difference.
Speed limit on railway curves (use of superelevation on railways) introduction when a train rounds a curve, it has a tendency to want to travel in a straight direction and the track must resist this movement, and force the train to turn. The opposing movement of the train and the track result in a number of different forces being at play.
