Yes, in many places rail lines share track, that is the case with Amtrak they don't own the tracks but have trackage rights to use the lines. Where trains go cross country like an intermodal train is operated by Union Pacific from Los Angles to New Orleans designated UP ZLAJX-10 (Z=highest priority-LA=Los Angles-JX=Jacksonville-00=date originated) In New Orleans the entire train is handed over to CSX-then takes their train now designated Q180 the rest the way to Jacksonville with CSX crews.
Wow Ponce De Leon, Florida lol but great video, I enjoy your videos, I'm a big fan of crossing signals too, usually if it's safe, and if I can find a good spot, I'll try to railfan at one with a mechanical bell! I'm on the hunt for one of those too
TrainmanKight-- I never knew Union Pacific ran trains down in Florida; are there any other southern states aside from Texas, Oklahoma, Louisiana, and Arkansas that they run trains through as well?
