On a hunch, Marion Collins took a giant tape measure last December and calculated the distance between light-rail and freight-rail tracks installed near her Minneapolis home for the Southwest light-rail line. Her hunch proved correct — and it turned into the latest problem dogging construction of the $2.9 billion transit project.
Collins knew the distance between the center of one set of tracks to the middle of the other was designed to be 25 feet to separate light-rail and freight trains along a narrow stretch of the route. But her measurement found the distance was nearly 11 inches short of the mark.
That means the 200 light-rail trains traveling through the Kenilworth corridor every day will be nearly a foot closer to nearby freight trains, which often carry hazardous materials such as ethanol. The project, about 80% complete, is slated to begin service in 2027.
“When there’s a collision, our neighborhood will become a big black hole,” Collins said in a recent interview. Other neighbors, donning tape measures and a healthy sense of skepticism, came up with similar measurements as well.
In an interview with the Star Tribune, Southwest Project Director Jim Alexander said, “we have to figure out what happened and see what we can do about it.” He told members of the Metropolitan Council last month, after KSTP first reported the problem, that the fix could happen later this spring or early summer and it won’t affect the project’s overall price tag.
Alexander said his staff took their own measurements near the W. 21st Street station and found the tracks are seven inches short of 25 feet. Either way, the tracks were installed too close to one another.
The co-location of light-rail and freight trains in the narrow corridor of Minneapolis has long been a challenge for the 14.5-mile extension of the Green Line, which will link downtown Minneapolis with Eden Prairie. An early design of the route called for freight trains, operated by Twin Cities & Western Railroad (TC&W), to be routed through St. Louis Park, leaving the Kenilworth corridor with just light-rail trains, and a bike and pedestrian path.
But St. Louis Park residents fended off the proposed alignment a decade ago, leaving transit planners to figure out how to squeeze freight, light rail and the bike and pedestrian path in Minneapolis. This led to a tunnel being added on part of the route for light-rail trains, a complex option that caused the project’s budget to more than double since 2011, making it the most-expensive public works project in Minnesota history.
