INDIANAPOLIS (AP) — Indianapolis city officials have decided not to provide any additional money to subsidize an Amtrak passenger line between Indianapolis and Chicago, casting its future into question. Under the subsidy deal, the Indiana Department of Transportation, Indianapolis and six other local governments agreed to pay a $2.7 million subsidy to Amtrak after the passenger train agency announced it was ending funding for passenger lines shorter than 750 miles. The city's decision to provide no additional funding comes after INDOT recently announced that a private vendor, Corridor Capital, had been selected to run the line and improve service along the 196-mile route. Corridor Capital has promised changes, ranging from cleaner cars, modest food service, Wi-Fi, and on-time service — goals Amtrak was supposed to have reached by now in order to continue receiving state, county and city support.
