The problem is that at several moments during the video, the player avoid freight cars going in the opposite way and threatening to hit him on the lines. And while riding on a rail, Vox Populi partisans were riding on the line's second rail but in the opposite way. And last things, people riding with Sky-Hooks are moving faster than the freight cars.

How could the Sky-Lines give movement to all these things?
