Existing Situation
The Project Team has identified these rail and road traffic problems in the communities:

Delays at the Forest Hill Junction
75th Street and Western Avenue
The north-south CSX railroad tracks cross the east-west tracks of three other railroads at this location, causing delays for freight and passenger trains waiting for other trains to cross.

Delays at the Belt Junction
near 75th Street and Loomis Avenue
Five railroad tracks converge onto two tracks at this location. Most trains need to cross to another track, much like changing lanes on a highway. Usually, only one train is able to pass through this junction at a time.

Delays at the 80th Street Junction

near 80th Street and Wallace Avenue
Six tracks converge onto two tracks at this location. The total train traffic is more than the railroad tracks can handle, which causes freight and passenger trains to back up.

Junctions are Too Close Together
throughout area
Due to the length of most freight trains, a train cannot stop for one junction without blocking another junction. To prevent gridlock, trains must wait beyond the project area so the junctions remain clear. This stopping and re-starting causes delays and limits the amount of train traffic that can pass through the area.

Environmental Issues
throughout area
Idling trains can create noise and air pollution.

Delays for Drivers and Pedestrians at
71st Street Crossing

71st Street near Bell Avenue
At this rail-street crossing, drivers and pedestrians using 71st Street must wait for trains to pass. This crossing may also present a safety risk for drivers and pedestrians.

Some viaducts in the project area are in poor condition.

Poor Conditions at Viaducts
along 75th Street rail corridor
The poor conditions at some viaducts—bridges where road traffic crosses underneath railroad tracks—can cause safety issues for drivers and pedestrians.

Limits on Metra
the SouthWest Service line
Metra’s SouthWest Service runs on only one track located near Wrightwood Station to Western Avenue. This limits the flexibility and reliability of Metra service.

Metra Conflicts with Freight Trains
Metra trains cross freight train tracks at several locations within the study area, including the Forest Hill Junction and the Belt Junction. There are also conflicts between freight rail lines and Metra’s SouthWest Service in the shared corridor between the study area and Union Station. During peak commuter periods only Metra trains are allowed to run in these areas. As a result, freight trains—and sometimes Metra trains—may encounter lengthy delays.
