Railfanning the BNSF ''Racetrack'' at Harlem Avenue, IL March 11, 2024. BNSF, METRA, AMTRAK 

Spotted for a few hours on a beautiful spring day in March (from 12 to 3 pm)
Filmed with a gopro hero 12. In order to keep space on my SD card for the rest of my vacation, I did not film until the end of most trains.
