Franken sent Obama a letter calling for the president to appoint a senior official to coordinate efforts to address rail monopolies and to suggest federal policies that could alleviate the problem.

In the letter, Franken cited analysis showing that only one freight rail company serves 78 percent of railroad stations within the United States.

“This lack of competition in our national freight rail transportation system and the resulting railroad monopoly power over a significant portion of annual railroad freight movement create significant problems for our state and national economies,” Franken wrote.

Franken said that more freight rail competition would help increase U.S. exports and create jobs.

“I believe strongly that efforts to grow our national economy and create jobs are hampered by the freight rail monopoly problem,” Franken said. “I look forward to working with you to address this problem in the coming Congress.”
