$30 Billion Denver to Vail Electric Train Proposal Faces Rocky Terrain
A $30 billion private proposal for an electric train from Denver to Vail faces skepticism over two massive tunnels and unfiled plans, prompting debate on the feasibility of rapid resort access.

Aspen —The wind off the Continental Divide bites at your cheeks, carrying the faint, metallic scent of snowmelt and diesel fumes that cling to the air near Fremont Pass. Here, where the landscape fractures into jagged granite ridges and deep, shadowed valleys, the idea of a smooth, silent electric train gliding through the rock feels less like engineering and more like magic. But magic, as any local knows, usually comes with a price tag that makes your stomach drop.
That price tag is currently estimated between $28 and $33 billion.
Jay Branch, vice-president of Denver West Express Inc., is the man standing in front of the blueprint. He’s not hiding behind the ambiguity; he’s leaning into it. “This is a concept, and it’s a business plan. It isn’t a fully engineered route,” Branch told the Vail Daily. “There are some problems that will need to be resolved. We haven’t solved all the problems. We know we can get from point A to point B in an efficient and reasonable amount of time. There’s a lot of questions that haven’t been answered yet.”
It’s a rare admission of uncertainty from a developer, and it’s worth the pause. The route itself is a beast: 178 miles of track stretching from Denver International Airport, threading through Littleton’s Mineral Station, dipping into the rural quiet of Bailey along U.S. Route 285, and finally bursting out into the resort towns of Frisco and Avon. The promise is speed — averaging 90 mph — and time saved. Ninety-seven minutes from the airport to the slopes. For a skier dragging bags through a parking garage at 4 a.m., that’s not just convenience; it’s relief.
But the geography is unforgiving. To get there, the proposal calls for two massive tunnels: a nearly 5-mile bore under the Continental Divide and a 6.5-mile tunnel near Fremont Pass. The trains would run on battery electric locomotives, technology similar to what Wabtec Corporation develops in Pennsylvania. It’s clean, modern, and expensive. And right now, it’s just a drawing. No official plans have been filed with the Colorado Department of Transportation or any other transit authority. The ink isn’t dry; the paper might not even be on the desk yet.
Skepticism is thick in the valley air. Patrick Brower, founder of the Grand County-based consulting service Grand Enterprise Initiative, looked at the proposal and saw the weight of the rock above. “It sounds like a pipe dream, or should I say tunnel dream - to me,” Brower wrote in a column for the Sky-Hi News. “But I’m curious to learn more.” That curiosity is shared by many, but so is the doubt. Can private investment carry the load of a $30 billion infrastructure project? Branch hopes so, aiming to fund as much as possible through private channels while collaborating with local, state, and federal entities. It’s a tall order, and the road to Avon is steeper than it looks from the map.
The silence of the electric train is a fantasy for now, but the noise of the debate is real. As the snow piles up against the windows of the ski lodges in Avon, the question hangs in the cold air: will we ride it, or will we just watch it pass? The answer isn’t written in the rock, but it’s waiting to be carved. Until then, the only sound is the wind, whispering through the pines, reminding us that the mountain doesn’t care about our schedules. It just stands there, solid and indifferent, while we argue about how to cross it.
