lol, watching top gear now..... they pulled a train with a Ford pickup..... big deal, I used to move them with one hand (just takes one to pull the throttle and release the brakes)

. We moved 3 flat cars once by hand, moved the first one with about 5 people pushing.... then we got smart and used leverage to our advantage.... really not that bad once you get it rolling. Bad thing is when you realize those old cars that have been sitting for years in a scrap yard have no brakes
