I always thought the Baldwin DR-6 "Baby Face" locomotive models were considered to be the "cutest" locomotives by most railfans.
Apparently, Baldwin didn't think the "Babyface" style looked so good. They made a running production change from the "Babyface" styling to the "Sharknose" style carbody.
To someone used to seeing EMD and ALCO cab units, the "Babyface" looked very distorted in proportions. I think the problem lay in the ratio of height to width. The roof of the Babyface cab is lower than the roof of the carbody behind it. This gives the cab a "squished" appearance.
Baldwin should have hired an industrial stylist to design the carbody for those things, someone who understood the esthetics of proportion. EMD, ALCO, and Fairbanks-Morse did. A running production change in styling is an admission something went very wrong indeed. The corrected design, the sharknose, is a classic based on the T1.
