Folks, the railroad buffs among you will know that a late 20 car passenger train is a heavy consist. Any such train would have been double-headed back in the day, or would have been given 3 EMD E units.
The Class J 611 in the video is one of the very last steam locomotives built. She was very modern when built in 1950 or so. She probably develops around 5,500 drawbar HP.
