Worlds Largest Operating Steam Locomotive

That's some beast.

big boy is the heaviest. but i dont think he is the biggest

not for much longer. 4014 big boy will take that mantel

true American Americana right here man, love it!!

me so suprise wish the train steam

My right ear was happy hearing this giant

a model of efficiency. only needs to be so large due to at best using about 10% of the steam to do anything. Also, a fine example of "clean coal".

Holy cow,what a wonderful sight!

What do you yhink I felt like as a young lad actually stending up wiyhin 2 ft of a steaming, panting 38 class locomotive just before depature to the record speed run to Melbourne in 1956 I think can anyone add more; AWESOME never forget it.

1:19- A hole of the day. I've had a few of those. Wish I had a brick at the time.

not for long. 4014 bout to be on the rails

Is this train still running today. If it is don't tell Obama and the EPA...all that carbon pollution and all.

That's a big snortingozooma for sure

I wonder if that idiot has been punched in the mouth yet.

....for now. UP is putting a big boy back into service.

Must have a seriously large minimum curve radius. I can't imagine it could run onto many city systems.

one has to admit, steam locos have personality !

sexy

ah those lovely days when steamies rule the rails

those people are standing too close to that train
