Where were the urban planners when the Pepsi Center was built (and now other buildings) that obliterated the direct run through track the Rio Grande and Santa Fe used to head south from the station. The convoluted move they would now have to use adds time and increases probability of freight train interference. It could have been incorporated so easily into the Center’s construction and perhaps provided rail access to events there.
When the Santa Fe was running LaJunta to Denver it took about 4 hours for the 185 miles. Using the SWC schedule for connections it might be possible for a crew and engines to make a same day turn from LaJunta to Denver but probably need another set of equipment with the cleaning required. This is certainly a viable project. The hurdle will be UP/BNSF concurrence but with the decline in Powder River coal perhaps it could be done. While each railroad has mostly single track they operate it jointly so it is effectively a double track railroad to Pueblo. Pueblo union station is still in use but not sure about Colorado Springs. No doubt changes for ADA compliance will be needed.
Originally the urban planners were part of the problem. As Wilbur "Sonny" Conder said in 1973, "the only thing worse than a private developer is a public developer."
We don't have room for all the details, but what we have now took almost exactly thirty years to develop. On the front end, in the administration of Mayor Federico Peña, ALL - repeat ALL - tracks were to be stripped from DUS; the central portion of the historic building was to become the atrium of twin high-rise towers. Various alternative sites were tossed into the pot whenever anyone questioned this. The only one that was feasible from a technical standpoint would have prevented construction of Coors Field. From a marketing standpoint it would have been a disaster. (Keep in mind that it was considered to be a big joke that Denver would ever build rail transit.)
It was never clear as to who was doing what, but it
was clear that the City''s objective was to get somebody else to pay for relocating Amtrak and constructing "roadsnbridgez" into the cleared Central Platte Valley. That somebody else, the planners, engineers, and politicians said, might be Amtrak or the Regional Transportation District. When a journalist finally figured this out, the upset promoters went through Washington, DC to stop Amtrak spokesperson Art Lloyd from saying that Amtrak did not have a budget for getting out of DUS.
What is there now is a compromise, with a convoluted funding plan that gave the City and developers a majority of the say (see "Dolllars Flow" PDF from 2009). But, Amtrak and the RTD were able to find allies in ColoRail, NARP, private car owners, tourist and restaurant businesses. A few far-sighted individuals like micro-brewer John Hickenlooper and longtime local politico Dennis Gallagher were able to visualize a revitalized station as the hub of the Rocky Mountain Empire. Had the developers had their way at a dozen turns of events, Denver could have become another Richmond or Saskatoon.
