He discussed, in detail, the relative ease with which the <a href="/wiki/U.S._government" class="mw-redirect" title="U.S. government">U.S. government</a> could build a tube shuttle system using technologies available at that time. Maglev being poorly developed at the time, he proposed steel wheels. The chamber's door to the tube would be opened, and enough air admitted behind to accelerate the train into the tube. Gravity would further accelerate the departing train down to cruise level. Rising from cruise level, the arriving train would decelerate by compressing the rarefied air ahead of it, which would be vented. Pumps at the stations would make up for losses due to friction or air escaping around the edges of the train, the train itself requiring no motor. This combination of modified (shallow) <a href="/wiki/Gravity_train" title="Gravity train">gravity train</a> and <a href="/wiki/Atmospheric_railway" title="Atmospheric railway">atmospheric railway</a> propulsion would consume little <a href="/wiki/Energy" title="Energy">energy</a> but limit the system to subsonic speeds, hence initial routes of tens or hundreds of miles or kilometers rather than transcontinental distances were proposed. <sup id="cite_ref-10" class="reference"><a href="#cite_note-10"><span class="cite-bracket">&#91;</span>10<span class="cite-bracket">&#93;</span></a></sup> </p><p>Trains were to require no <a href="/wiki/Railway_coupling" title="Railway coupling">couplers</a>, each car being directly welded, bolted, or otherwise firmly connected to the next, the route calling for no more bending than the flexibility of steel could easily handle.
