The news: In February, the Chicago Transit Authority eliminated nine express bus routes and reduced service on seven rail lines in an effort to cope with its budget shortfall. Behind the news: Although the CTA served 80.7 percent of the Regional Transportation Authority riders in 2008, it is set to receive 44 percent of the 2010 operating budget. Metra, on the other hand, had 13.5 percent of the RTA ridership in 2008 but is set to receive 27. 3 percent of the budget. The disparity, in part, was the basis for a muchpublicized lawsuit filed in January against the RTA and the Illinois Department of Transportation by two CTA riders alleging racial bias in the distribution of funds.
