Question: 1 / 400

What does "Degree of Curve" refer to in railroad terms?

Angle subtended by 100 ft. arc

Angle subtended by 100 ft. chord

The term "Degree of Curve" in the context of railroad terminology specifically refers to the angle subtended by a chord length of 100 feet. This measurement is crucial in understanding how sharply a curve bends along a track.

Using the chord length of 100 feet allows for a standardized way to quantify the curvature of railroad tracks, which is important for ensuring the safety and efficiency of train operation. The degree of curve provides a clear numerical representation of curvature, making it easier for engineers and surveyors to plan track layouts and assess the impact of curves on train handling.

While other options may refer to different chord lengths or angles, they do not conform to the industry standard established for railroads. The focus on a 100-foot chord fits into the established practices in surveying and track design, ensuring consistency across different engineering applications.
