West of Denver, the railroad begins leaving the plains behind and heading toward the foothills.
The District
The railroad, the tunnel, and the Colorado landscape behind the name Tunnel District.
The Moffat Road west from Denver toward the Continental Divide.
The Moffat Road
David Moffat had an ambitious idea: build a railroad directly west from Denver through the Rocky Mountains.
The Denver, Northwestern & Pacific Railway began building west from Denver in 1903. The ultimate ambition was Salt Lake City, but between Denver and the country to the west stood the Continental Divide.
The railroad that became known simply as theMoffat Road would eventually give its name to one of Colorado's great railroad engineering projects.
The Rollins Pass Route
Before trains could go through the mountain, they had to go over it.
The line over Rollins Pass was intended as a temporary route while a tunnel through the Continental Divide could be financed and built. Instead, the spectacular mountain railroad remained an essential part of the route for more than two decades.
Steep grades, tight curves, high elevation and Colorado winter weather made the route difficult and expensive to operate. Snow sheds, rotary plows and constant battles with drifting snow became part of life on the hill.
The Moffat Tunnel
In 1928, the railroad finally went through the Continental Divide instead of over it.
The 6.2-mile Moffat Tunnel transformed the route. Trains no longer needed to make the long, difficult climb over Rollins Pass, eliminating roughly 23 miles of mountain railroad and making the crossing faster and far more dependable.
The old hill route was abandoned, but its grade, tunnels, cuts and other remains still trace the railroad's remarkable path across the mountains.
Along the Line
The railroad is also a string of places — communities, landmarks and railroad locations that give the route its character.
West of Denver, the railroad begins leaving the plains behind and heading toward the foothills.
A small mountain community along the railroad as the line works its way deeper into the Front Range.
A gateway to the historic Rollins Pass route and one of the communities closely associated with the Moffat Road.
Once an important railroad location on the climb toward the Divide, and even a destination for summer visitors arriving by train.
At the head of the valley, the railroad disappears beneath the Continental Divide through the Moffat Tunnel.
The Line Today
The Moffat Road did not disappear with the opening of the tunnel. Its mountain corridor became part of a larger railroad system, and trains still follow much of the route west from Denver and through the Moffat Tunnel today.
The names have changed. The locomotives have changed. The reason for crossing the mountains has not.
Why Tunnel District?
Tunnel District started with a railroad, but the site has grown into something broader.
It is a place for railroads and projects, certainly, but also travels, photographs, experiments, stories and memories. The Moffat Road provides the geography. The tunnel provides the name. What ends up here depends on where curiosity leads next.
