Daily Trains Affected

125 freight trains (UP, CSX, IHB, NS, CN)

2 Amtrak (Cardinal Service)

Communities Benefited:

  • Dolton and Riverdale


The project will increase freight train speeds for multiple routes from 15 mph to 30 mph, including routes accessing CSX Barr Yard, UP Yard Center, UP Dolton Intermodal Yard, a CSX mainline route, and all mainline connections between IHB, CSX, and UP. The increased speeds will enable this location to handle increased freight train throughput. Due to increased freight train speeds the potential for delay to Amtrak trains will be reduced.
