Midwest hub for HSR: Union Station or a new facility?
"Union Station is a poor candidate to serve as a high-speed rail hub.
Despite the soaring image of its barrel-vaulted Great Hall, the passenger concourse east of the hall is confusing and confining, a warren trapped within the structural columns that hold up the office building above it. Going forward, Union Station lacks adequate space to marshal more passengers and handle more trains. Nor does it connect to the Chicago Transit Authority’s express service to O’Hare. Its fundamental problem, though, is that it isn’t really a station. It’s a terminal.
Almost all of Union Station’s tracks, whether northbound or southbound, stop at the station instead of running straight through. That’s no good if you’re a high-speed rail passenger traveling, say, from Milwaukee to Cincinnati. You’d have to change trains in Chicago. Who has time for that? You’d fly instead."
