Speeds would likely be around 80 miles an hour, which is similar to the A-Line from downtown Denver to Denver International Airport.
Charles Albi, the former Colorado Railroad Museum Director. . . . says acquiring land to build a new rail line would be extremely costly and difficult, so state officials will likely have to convince BNSF to let them use the existing line.
"It's not like back in the day where you had wide open prairie, and you could build anywhere you wanted," he says.
Similar routes exist between Milwaukee and Chicago, and in the Pacific Northwest between Seattle and Eugene, Oregon.
"People talk about the great trains in Europe and in China. There's a reason for that. Population density. And we're getting to that point," says Albi.
CDOT officials do not have a price tag for the project yet, and say the earliest we could see it in place would be 2023.
From here.It's also unclear how it will be funded.
At 80 miles per hour, before considering time lost to load and unload passengers at stops along the way, running parallel to a highway with large portions that have a 75 mile per hour speed limit, this is a very expensive project that is better off not done at all. Heavily subsidized buses along the line of existing Bustang service would be a better deal and provide similar service time and quality.
I am not saying that high speed rail isn't worth considering.
The corridor from Fort Collins to Colorado Springs has enough population density to support a passenger rail line (although it does not make sense along the low traffic and already very fast stretch from Colorado Springs to Pueblo). Flying is very hard to make competitive at those distances due to time spent going to and from airports to final destinations and security and boarding delays. But, to be an attractive alternative, a front range passenger line needs to be able to go much faster than 80 mph and needs a dedicated rail line that doesn't have to interface with roads and highways or with other slow speed trains on existing tracks.
If you spend what it takes to get speeds of 140 mph to 220 mph, which is the current state of the art for high speed rail, the improved service would divert a lot of I-25 traffic, and would add value in the connections between Colorado's big Front Range cities.
