It is no secret that many of America's roads and railways are badly in need of repairs.<br /><br />But there's disagreement on how to pay for the work that needs to be done.<br /><br />In Chicago, where half the rail freight in the United States rolls through. the tracks are so tangled that <br />rail officials have given it the name of "spaghetti bowl"<br /><br />It takes a freight train two days to travel the 3,000 km to reach Chicago from Los Angeles.<br /><br />It can take another day or two just to get through Chicago,because passenger and freight trains share lines. <br /><br />America’s antiquated infrastructure can have dramatic consequences.
