Norfolk Southern Corp. says it’s restricting the speed that Amtrak trains can run on tracks the railroad company owns between Dearborn and Kalamazoo even as the line is prepared for high-speed passenger rail.

Norfolk Southern spokesman Randy Husband told AnnArbor.com that the company would only pay the maintenance costs necessary for the tracks to handle trains traveling between 25 and 60 m.p.h. He says someone else will have to pay for increased maintenance costs that would come with higher speeds than freight trains run.

Amtrak spokesman Marc Magliari says the federal money Michigan is receiving to improve the tracks will correct the problem.
