A platform for research: civil engineering, architecture and urbanism
For ordinary railroad purposes, the transition curves in common use are of about equal utility. All require tables, and, with these in hand, can be readily staked out. When, however, we are confronted with the task of designing and detailing for the shop, track-work such as turnouts and crossings, new problems arise. The multiple compound curve requires a maze of complicated computation when applied to this class of work (in which loci are absolutely necessary). The cubic parabola appeals to the writer as the simplest curve which will fulfill the conditions of a transition. But, it has been urged by some that the cubic parabola is not a true transition curve, nor can it be readily staked out with a transit.
