CHICAGO — Metra’s own testing of toxic diesel exhaust inside its passenger coaches shows the transit agency’s pollution problems are more extensive and worrisome than it has publicly disclosed, according to records obtained by the Chicaog Tribune.
Metra’s testing summary, obtained under the Freedom of Information Act, shows the worst pollution generally was on trains leaving the south platform at Union Station. The highest soot levels on a single route were on a train leaving the Ogilvie Transportation Center. Higher-than-normal levels also were detected on outbound trains from the LaSalle Street Station.
