What a monster Daniel, its like the 'Titanic' on rails. Shows the ingenuity of man doesn't it.
Ingenuity of man .... Yes, but even more to the point in my mind, is that it well shows the true POWER of STEAM!!!
This single locomotive could pull a mile of heavily loaded rail cars up a relatively steep grade in a blizzard, and it hasn't been until fairly recently that diesel / electrics have been able to match that drawbar pull.
