Aesthetics
Earlier passenger diesels, like the EMD E8, ALCO PA, FM Erie-built and Baldwin Sharknose, were streamlined cab units designed for good looks and the appearance of speed. The SDP40 instead has the rugged appeal of a high-horsepower road-switcher. This look was contemporary to, and eventually overtaken by cowl units like the GE U30CG and EMD FP45, SDP40F and F40PH.
Visually, the SDP40 is a hood unit distinguished only by the shape of its rear end behind the radiators, with its flat end having no number boards, shuttered boiler air intake on each side, extra exhaust stacks over the boiler, cantilevered walkway around the flat end, and very steep rear steps. EMD applied this same end to the passenger SDP35, SDP45, and GP40P locomotives, as well as the freight DD35, DDA40X and SD40T-2.
Amtrak's SDP40F locomotive, although sharing several mechanical specifications, is visually a much different locomotive. Seven years separate their introductions, and the SDP40F was actually based on the SD40-2. It had a full-width carbody, similar to the FP45. It was also six feet longer than the SDP40.

Famous quotes containing the word aesthetics:
“Nothing is beautiful, except man alone: all aesthetics rests upon this naïveté, which is its first truth. Let us immediately add the second: nothing is ugly except the degenerating man—and with this the realm of aesthetic judgment is circumscribed.”
—Friedrich Nietzsche (1844–1900)
“For aesthetics is the mother of ethics.... Were we to choose our leaders on the basis of their reading experience and not their political programs, there would be much less grief on earth. I believe—not empirically, alas, but only theoretically—that for someone who has read a lot of Dickens to shoot his like in the name of an idea is harder than for someone who has read no Dickens.”
—Joseph Brodsky (b. 1940)
“What is the use of aesthetics if they can neither teach how to produce beauty nor how to appreciate it in good taste? It exists because it behooves rational human beings to provide reasons for their actions and assessments. Even if aesthetics are not the mathematics of beauty, they are the proof of the calculation.”
—Franz Grillparzer (1791–1872)
