Trains on Chicago's Metra commuter railroad typically arrive on schedule at least 95 percent of the time, according to statistics the Metropolitan Rail Corporation provides. During the first nine months of 2015, 95.8 percent of Metra trains arrived on time.
Metra typically achieves or comes close to its stated goal of at least 95 percent on-time performance; however, this does not mean that trains necessarily arrive exactly at the stated time. Commuter railroads consider any train that arrives within six minutes of its schedule time to be on time.
Metra is the fourth-largest commuter rail system in the United States. The system offers commuter rail service on 11 different lines in the Chicago area, including service to stations in Indiana and Wisconsin.
