The item comments upon early standards for alignment and superelevation of curved track and extracts from the text of Technical Booklet No. 11 "Speed on Curves." Portions of the extract include information related to the determination of the permissible rates of change of cant and diffusing, and their relation to the form and dimensions of the transition curve of the track. A portion of the booklet is devoted to the consideration of curves without transition, and formulae are developed which cover permissible speeds through crossover roads, double junctions, and reverse curves.
