That long distance train is the crescent, only train 20, not 19, anyways, it was downgraded a couple years ago to stop at BWI airport, Princeton junction,New Brunswick and metropark, now it got downgraded to only stop at BWI and metropark, the whiring nose for like the track are like the sounds of the rail grinding I think. Apologies for the late reply
that’s the Crescent train 20. unfortunately Amtrak had downgraded the schedule again, the decided to add BWI, PJC, NBK & MET to 20's schedule, which makes entirely no sense at all, it's a long distance train it supposed to be discharge only after it leaves Alexandria or Washington, DC, idk why schedules keep being downgraded
