After the lessons of rail, the Denver region might just be ready to move into a bus-centric transit future that better addresses climate change, air quality, and inequity. But there's one unfulfilled promise standing in the way: the Boulder train. Is it time for locals to let that go, or is there hope on the horizon? Part 4 of 4.

The Denver metro area's rail system mostly neglects the dense, walkable parts of the city. Why is that? And now, after we've spent decades prioritizing freedom in how we get around, is it time to change the way we live? Part 3 of 4.

Sam Chesser loved the transit system when he visited New York City. So Sam, like many voters, supported a vision he thought would make his beloved hometown, Denver, just as accessible. That allowed transit planners to spend billions of dollars laying rail track. But almost two decades later, who actually uses it? Part 2 of 4.

With a brown cloud hovering overhead and a second-place football team, Denver had dreams of becoming a world-class city. But it wasn't until the turn of the millennium that it found a way to get there: trains. Part 1 of 4.

In 2004, Denver-area voters backed one of the most ambitious transit projects in the U.S. This plan called for a sprawling network of new rail lines that would help commuters glide by clogged roadways and transform Denver into a world-class city. But as train lines opened, some uncomfortable truths emerged: The trains aren’t very useful to most people. The trains have done relatively little to shift how people move around the region. And they cost a lot of money.
 
Denver’s love affair with trains is one of shared dreams and unstoppable personalities. It’s the story of billions of dollars and gleaming new infrastructure for a city on the rise. And for one particular corner of the metro area, it’s a story of disappointment and betrayal.
 
Ghost Train is the story of how one polluted, traffic-choked city went all in on trains, and what happened when that plan jumped the track.

Nathaniel Minor, the transportation reporter for Colorado Public Radio, has spent years trying to understand this anger, what these trains were meant to accomplish and whether they’re succeeding. But this story is about so much more than one train system in Colorado. Because Denver’s not the only place opening new rail lines. Cities all across America are turning to rail to face down big issues like climate change, traffic and inequity.
