Abstract The author outlines the problem confronting the railroad-train designer in providing the comfort and beauty which the passenger has come to expect, and which is necessary to attract his patronage in the highly competitive field of modern transportation. The over-all design conception is discussed, with decorative treatments described of such famous trains as the Olympian-Hiawathas. The author’s conception is given of the facilities and styling of passenger cars of various types which will make up the “train of tomorrow.”
