If there were more backpackers willing to ride trains in Colorado, the Ski Train from Denver through the Moffitt Tunnel would run year round and not just during the ski season.
Maybe so. Closer to the mark might be that in places where there are frequent trains to nearby backpacking country, relatively many backpackers will ride them, but backpackers aren't going to turn out in numbers to support frequent train service by themselves. The what-if question about hikers, backpackers, and general outdoorsiness isn't so much about the max once or twice a day ski train route, but about a hypothetical extension of the W-Line light rail a couple of miles northwest to some trailheads.
Back to topic: Isn't the key thing about whether a Front Range train (or ideally 2 or 3 or 4 trains a day) would get enough passengers to bring their subsidy down to whatever level someone thinks is acceptable this: are there 250, 500, 750, 1000 people a day who want to go from someplace near one of the stations to someplace near another of the stations. It doesn't matter if half or three quarters or ninety percent of the daily commutes or typical business daytrips or whatever start or end in a suburban office complex far from any station, as long as there are enough typical trips that end near a station. Denver may not have all its business concentrated in a mile radius of station like Boston in 1925, but Denver absolutely has a busy, dense downtown around the station, with business and pleasure destinations and good local public transit and not completely cheap or pleasant parking. Denver isn't Phoenix. If the Illini/Saluki "work" then a train in and out of Denver should work just on the strength of downtown Denver, even if most of the potential passengers drive to the station at the other end of their trip. The Old Depot at Colo Spgs looks to be in a pretty lively business district but no more than half a mile from the edge of residential neighborhoods in both directions, ie there are even potential walk-to passengers living in Colo Spgs (I don't know Colo Spgs, unlike Denver, so I'm going on satellite views here.
) Etc. Etc. down the line. DUS is a bit of a problem; the state might do better to find a way to run this train in and out via one of their commuter lines rather than through the BNSF yard that ties up the CZ so much; too bad about the south tracks at DUS being all gone.
Maybe. Not sure.
