CSX X409, An Over 800 axle Manifest

The longest CSX Manifest I've captured on video to this point in time , 816 axles. And it was also unique for this area with Two Lead and two DPU Locomotives. All four under power. A LONG train on a real busy day. Not sure if its a seasonal thing or a reaction to shifting patterns because of the Baltimore port calamity, but there are MORE and LONGER trains on this main line that I had seen last year this time frame

Neither, it's a detour related to work on the Howard Street Tunnel in Baltimore.
