Heritage Corridor
suburban rail line in Chicago metro area
The Heritage Corridor (HC) is a Metra commuter rail line in Chicago, Illinois, and its southwestern suburbs, terminating in Joliet, Illinois. While Metra does not refer to its lines by colors, the Heritage Corridor appears on Metra timetables as "Alton Maroon," after the Alton Railroad, which ran trains on this route. The name Heritage Corridor refers to the Illinois and Michigan Canal Heritage Corridor. Established in 1984, it runs parallel to the line.
Unlike other Metra lines, the Heritage Corridor runs during weekday rush hours only in the peak direction–to Chicago in the morning and Joliet in the afternoon, with the trip from Joliet to Union Station taking about 1 hour and 7 minutes. The Rock Island District also serves Joliet with 21 trains.
As of February 15, 2024, Metra operates six trains (three in each direction) on the Heritage Corridor on weekdays, with each train serving all stations on the route. All inbound trains originate from Joliet in the morning, and all outbound trains terminate at Joliet in the afternoon. Except for occasional seasonal excursion services, there is no Saturday service. There is currently no off-peak, Sunday, or holiday service on the Heritage Corridor.

Why this record matters
“Heritage Corridor” is worth following because a concise public description often conceals a longer documentary argument. Here, Heritage, Corridor and suburban provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jun 12, 2026. The linked authority identifier is Q5738778. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1984 and 2024.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
