About 10 times each day, giant freight trains pass along a narrow section of track along the Sacramento River in far Northern California where engineers on the locomotives regularly tense up with stress.

"Every single time, it's a near miss" of a train hitting a person, said Ryan Snow, the California State Chairman of the Brotherhood of Locomotive Engineers and Trainmen. "Multiple near misses, every single run. My nightmare is that a family that isn't paying attention gets hit."

This particular stretch of track, which wends north from the town of Dunsmuir, is a renegade route for hikers to one of northern California's most enchanting natural sights, Mossbrae Falls. Fed from glaciers on Mount Shasta, the water pours out of lava tubes and down mossy cliffs, forming a verdant and ethereal cascade into a calm, shaded swimming hole.

It appears magical. It is also inaccessible — unless visitors trespass more than a mile on the tracks or wade across the river. Accidents have happened. Two people have been struck by trains in the last few years (although both survived.) In May a Southern California woman drowned after trying to reach the falls via the river. But the tourists keep coming. Drawn by Instagram and Tiktok, increasing numbers of people have taken to visiting the falls — nearly 30,000 according to a city study, the majority of them by trespassing up the train tracks.

For years, outdoor enthusiasts in and around Dunsmuir have pushed Union Pacific Railroad, which owns the tracks, to work with the city to create a safe, accessible, legal path. But the effort has been dogged by delays.

This week, the train workers union decided to enter the fray, issuing a news release decrying the slow progress and calling on Union Pacific to do more to make the long-held dream of a trail a reality.

"Each month that goes by without a real construction timeline, lives are put at risk," Snow said in a statement. The statement also accused Union Pacific of "slow-walking" the project, saying railroad officials have called for meeting after meeting, but has never produced a right-of-way commitment or a clear construction timeline.

Many engineers, Snow said, are frustrated and feel the delay "unfairly endangers both railroad personnel and the public."

In a statement, Union Pacific said that the railroad had "approved the concept of a trail into Mossbrae Falls years ago, and we have been working with the City of Dunsmuir and the Mount Shasta Trail Association to find solutions that address everyone's safety concerns."

Earlier this summer, Dunsmuir city officials held a "summit" with Union Pacific officials to tour the falls and talk about the proposed trail connection.

City officials said the summit, which included representatives from local elected officials offices as well as railroad officials from Omaha and Denver, marked "a new milestone in the slow but steady process." A city news release noted that "key Union Pacific officials had the opportunity to see the falls for the first time, recognizing the importance of building public access to this beautiful natural resource."

But some longtime trail advocates said they were not convinced that the dream is any closer. John Harch, a retired surgeon with the Mount Shasta Trail Association and has been working with others for years on public access, said he still didn't see evidence of concrete progress.

"Here we sit, as before, while people risk their lives to see the falls," he wrote in an email.

Snow said he hopes the public can put pressure on the parties to make concrete progress.

"We've been lucky that we haven't had any fatalities caused by a trespasser strike," he said. "The worst thing an engineer can do is hit somebody. It's stressful."

Meanwhile, he said, the route is only becoming more popular. "It's in hiking magazines, and on the internet everywhere. It's attracting more and more people."

He added: "I can't blame them. It's beautiful."
