Sinopsis

Excerpt from The Transition-Curve Field-Book: Containing Full Instructions for Adjusting and Locating a Curve Nearly Identical With the Cubic Parabola in Transition Between Any Circular Railroad Curve and Tangent

In the investigation of the principles upon which the rules are based, it will be seen that with data consisting in great part of familiar approximations used in circular-curve location, and with no mathe maties beyond a little algebra and trigonometry, practically exact results are reached in regard to laws of the Transition Curve and its relations to circular curves.

By means of Transition Curves of less than 15° of central angle, tangents can be connected with all circular curves used on railroads, their combined location presenting little, if any, more difficulty than ordinary circular-curve location.
