Here's an alternate theory: Terminus did an excellent, almost expert like job at corralling Rick and Co into the railroad car. Has anybody taken into consideration the obvious? WHERE ARE ALL THE ZOMBIES? It isn't as if they're bashing down the fences like they were at the prison. they're nonexistent. Terminus could also be corralling all of the undead into that one location and then destroying them, and that could account for all of the bones.
Here's another theory: When I think of boxcars, I think of WWII concentration camps. The area where those skeletons were looked like a war zone. Maybe it was a mass execution. Maybe Terminus needs slave labor.
