the backhoe did not turn around and thy did not move the train. look at the color of the of the car that bh boarded first. notice the limbs of the trees. think in the space the back hoe has to operate. it would have to of moved down the car and onto the next one. look closely, there are three pivot points. the front bucket, the rear bucket and just behind the front axle. this guy could have "walked" the entire train emptying cars.
with the analysis behind.... put me behind the wheel, I WANNA do that!!!!!!!!
