I dont believe in these kinds of coincidences...this reeks.
Some protocol dictated that they be on a Train.
A bunch of legislators on a train after the SOTU isn’t normal practice. There was some reason they were being shuttled on train. Not a bus, not plane but a train. That’s just odd.
I do know that Trains are designed and maintained around certain scenarios. For instance, FEMA decides that 2 million people need to be moved along a piece of track, so they will contact the rail company to provide extra work and maintenance along that specific rail, or platforms every 4 miles instead of 10 or something.
They do this because trains provide a unique conveyance. So to see these people on a train tells me that some protocol was toggled.
