CHICAGO (AP) – Hundreds of Midwest manufacturers stand to benefit from a web of high-speed passenger rail routes emerging from Chicago’s rail hub, according to a report released by an environmental policy group that has fought to defend the use of billions in taxpayer money on such projects.

The report released Friday by the Chicago-based Environmental Law & Policy Center found that 460 manufacturers in seven Midwest states are poised to reap new business, along with a dozen more highly visible companies that make rail cars and locomotives. Those additional supply-chain manufacturers make everything from seats, couplers and bolts to ceiling panels, interior lighting and air horns. They also cut sheet metal, provide electronics and communications equipment, and supply track maintenance machinery.

“What we’re seeing is that old-line Rust Belt manufacturers are making the equipment for modern new rail cars,” the group’s director, Howard Learner, told The Associated Press. He said the “extraordinary” number of companies they found in the supply chain was nearly double what he expected.
