The Photo Standalone from The New York Times January 28, 1934, below, reports on the very first "Train of Tomorrow" designated by General Motors. What's in this picture's caption simply all the information (this Union Pacific train was built by GM) this company wanted to publicly release on the futuristic new direction GM was heavily starting to invest in. Also notice this commemorative coin handed out at the World's Fair of 1934 that had the Train of Tomorrow name emblazoned on it.

Further down at this section are a few 1934-35 General Motors print ads giving a subtle lead on the direction Harley Earl's futuristic engineering role was taking at this timewhile he was in charge of the all-new engineering designs behind all sorts of other transportation products, besides cars and trucks, for the world's largest manufacturer. After this company secured Designer-Earl's involvement, other GM leaders didn't talk up their new golden goose (design), with comments like this, "at this very moment, our newest GM division is presently working on 'startle the imagination' type engineering projects." But, as one can clearly see printed inside these ads below, GM was letting the information out --- subtly --- on how this company was aero-designing airplanes and trains, too. 

Also provided below, is a link to a transcribed interview Stanley Brams had with Harley Earl in 1954 whereby he talks about designing the original Union Pacific M-10,000 streamliner -- on page 6 and 7 -- and how it won him and his in-house GM Styling Section design team the contract for not only designing all GM's most important trains of the twentieth century [in the 1930s,'40s and '50s], but GM Styling designing the next "Train of Tomorrow" that publicly debuted in 1947, too. Again, Earl didn't want to risk raising too much awareness, in this interview w/ Brams because at this time in the mid-1950s GM had gained a "design monopoly" manufacturing many product-designs...from cars, busses and trains. {Read two different news stories directly below which quote the Justice Department saying, "General Motors produced 83% of the 3,233 buses made in this country last year", and "GM's ElectroMotive division in LaGrange, Ill., makes more than 80% of all the new and rebuilt railroad locomotives produced in the U.S.} 

After all, during the mid-1950s was when the U.S. Senate / Justice Department's antitrust investigation in Washington started focusing its trust buster cannons on GM to break it up. These articles show the "bigness" issue was real. Plus, like designing buses, Earl didn't want to share too much information on how he designed this ground breaking train back in the 30s...and how if someone ever dug deep enough...they might be able to connect all the dots and see how GM's newest train, like the Aerotrain, was just a direct descendant of the UP M-10,000, AND, these train designs directly tied him to also designing many of GM's war products and/or advanced weaponry for the Detroit Arsenal before, during and after WW II, etc... 

Men like  Alfred P. Sloan, Jr. and H.J. Earl always planned to keep the achievements behind this record making train subverted. So, they didn't mind if the history behind "who did what" slipped through the cracks of time. In a sense, they actually planned for it to happen this way...but that didn't mean of course that Harley Earl never (after he died) wanted to be associated to this important streamlining contribution in American history. He did. Sloan and Earl were seemingly after much bigger dreams and aspirations back in the beginning of the 1930s...that they both apparently fulfilled later on in their careers. Sloan was fingered as the business genius and Earl got credited with being the brilliant artist/designer. But in any event, the seminal history behind this important train has yet to be fully examined in our contemporary business world, society and culture. Again, essential parts and pieces of America's transportation history properly connecting this influential design work, which very much helped launch the modern design-in-industry era, has not been studied, reported on or most importantly...understood.
