While this may not be the most precise place to post this, what I saw likely ended up on the Tier somehow being this is about NS.
About 2 weeks ago, I was walking around Tift St Nature Preserve. Of course I walked along its edges overlooking both mainlines. While easily being able to watch CSX, NS was a bit more difficult as trains past through the yard. As I was watching, one NS train came through the yard and crossed CP-Draw. Kinda long but nothing extraordinary. But then I see another train coming along through the yard thinking he'd stop before crossing....he kept going. Only a few minutes behind the first one. After a few minutes, I'm beginning to realize that this is a really long train. As I'm standing there, I see another set of NS locomotives entering the yard and suddenly realize that they are connected to the train in front of it. And this second section is also really long! My guess is that as the first locomotive of this huge train is entering the Bison Yard, the last car hasn't crossed CP-Draw. BTW, this train was not assembled in the yard. I saw it come up well south of the yard. Can't imagine how annoyed drivers must have been at the Lake Ave crossing.
As far as I could tell, there were no crews in the middle locomotives. Lights were on.
Is this normal? Was NS just trying to get as many trains across the bridge as possible? Instead of getting 3 separate trains across, they connected two and therefore pushed 2 trains across?
