Elise Mead is part of a new generation of transit riders who will help make or break the struggling Northstar commuter line.

"It saves me a ton of money," Mead, 22, of Andover, said one afternoon last week as she rode the 3:57 from downtown Minneapolis.

Yet one person's savings can be another's expense.

Slashing fares encouraged more people to ride the Northstar this year, but the cuts nearly wiped out the revenue gains from the extra riders.

As a result, Northstar's government subsidies remain among the highest in the nation, paying for roughly 83 percent of the commuter line's cost.

"It's a little rich," said Steven Polzin, a director at the Center for Urban Transportation Research at the University of South Florida.

The Northstar's problems are largely rooted in its 40-mile route. The original plan was for it to run from downtown Minneapolis into St. Cloud, but lack of federal money forced it to end about 25 miles away in the much smaller community of Big Lake.

"It makes a lot more sense for it to terminate in a population center," said St. Cloud Mayor Dave Kleis, who promoted that plan when he was in the Legislature. "It should have happened."

Kleis said Minnesota's congressional delegation has supported relaxing federal requirements for funding the extension.

But the odds of that happening are "very remote … in the near term," said Brian Lamb, general manager of Metro Transit, which operates Northstar. "Everyone is focused on trying to make sure that the Big Lake-to-Minneapolis operation continues to show the kind of growth that we are seeing."

With ridership flagging, Northstar cut fares by $1 in summer 2012, shaving as much as 25 percent off ticket costs in an effort to stimulate interest.

Metro Transit says the discounts are a major reason Northstar ridership is projected to increase by 12 percent this year, from 700,276 to an estimated 784,000.

Unusually costly

More riders and lower expenses offset the fare cut. Total fare revenues rose from $2.56 million to $2.59 million. The average cost per passenger dropped from $22.91 to $19.81, with adult passengers paying fares of $2.50 to $6.

But they're picking up only 16.7 percent of the cost to operate the commuter train — about the same as last year — leaving taxes to subsidize the rest. Even in the heavily subsidized world of public transit, Northstar is costly.

"It is among the higher-cost systems," Polzin said. "That's not uncommon to the newer systems."

The percent of costs paid by passenger fares was lower at Northstar than at 19 of 24 commuter rail lines in 2012, according to the National Transit Database, which compiles statistics for the federal government.

The commuter lines that can rely more on fares for revenue tend to be in larger, more established markets. Metra Rail, which runs from downtown Chicago to far-flung suburbs, carried 74,246,584 passengers in 2012. Its ticket prices were only slightly higher than those on Northstar, but revenue from fares was enough to recover 48 percent of its costs.

Metro Transit officials prefer to compare Northstar's performance with eight commuter lines on the smaller end of the scale. But even most of those recovered a higher share of their costs from passenger fares than did Northstar.

In the Twin Cities, Metro buses and the Hiawatha light-rail line rely on passenger fares for 32 percent and 37 percent of their operating costs, respectively. Both make numerous stops throughout the day, while Northstar has seven stations with trains running only in the morning and evening rush hours.

Metro Transit officials said they dropped fares to entice more riders, not to raise more revenue.

The Northstar Corridor Development Authority concluded in 2010 that it probably couldn't persuade the federal government to fund an extension to St. Cloud, then estimated to cost $150 million, because expected ridership wasn't adequate.

The authority hopes the Northstar Link commuter bus service between St. Cloud and the Big Lake rail station will demonstrate enough demand for the commuter rail to justify federal funding to extend the line. The bus runs during early mornings and late afternoons.

Many riders are students

About one-third of the Link riders are students from St. Cloud State University traveling between campus and their family homes.

"The younger generation now choose not to be auto owners," said Tom Cruikshank, director of planning for the service. "They're making travel decisions to not bring a car to campus."

Dan Clark, a freshman at St. Cloud State from Hastings, is a good example. One evening last week he took the bus link to Big Lake where he caught the Northstar to Target Field station in downtown Minneapolis. He was planning to jump on the Hiawatha light rail to the Fort Snelling station, where his family would pick him up.

He had a table to himself in the Wi-Fi car of the Northstar where he was working on his laptop. "The Wi-Fi is fast," he said.

The commuter train hasn't caught on with every classmate he knows from the Twin Cities.

"I've talked to people who haven't considered this an option because they thought they could only go to Big Lake," he said.

Mead works at the University of Minnesota and picks up the Northstar at the Coon Rapids stop, nearest her home in Andover. Like many riders, she takes advantage of employer discounts that bring her monthly Northstar cost to $76 — about one-third what she says her parking costs would be if she drove.

"The day we had all of that snow, I still got in at the same time," she said.

Erin Flenner, 30, of Sartell, drives to the Big Lake station because she likes the convenience of having a car to run errands after returning on the Northstar from work in Minneapolis. "I wouldn't drive all the way," she said. "This is more relaxing."

Extending the commuter train to St. Cloud "would be huge for me," she said.
