(here/there) was the location where passengers boarded, near the temporary Amtrak station. Helen Bushnell, blogger for Train Star, completed a very helpful guide to Denver's Temporary Train Station, in place for the duration of DUSPA's remodeling of Union Station, due to end in 2014. She's put together a fairly decent travel guide in her post. Of note, she pays attention to details that are meaningful to most, including the disabled and the folks that are onboard and jumping off to grab a few items at the nearest convenience store. Thanks, Ms. Bushnell, for helping folks Travel by Train. If anyone is still looking for official information, here's the best available directions (PDF) and the site.
