The Big Boy is the largest articulated steam engine ever to grace the prairies, although heavy the Big Boy could go 80 MPH without hauling anything. Some might speculate that the Alleghany is the heaviest, although some facts are not what they seem. Nothing like Big Boy has ever been seen, only 8 remains in existance.

Here is a nice clip taken of when 4014 was stopped at Las Vegas on her return trip home to Cheyenne, WY to UP's shops so the rebuild can begin:…

The music playing during this clip, combined with the images brought tears to my eyes. ^^

Hehe, love this thought, a Big Boy sitting in Old Penn Station!  Thank you!

Please tell me:
Where did you get this particular photo of Penn Station? I haven't been able to find it anywhere

We're working on a HO model based on the Penn Station plans. The tracks and platforms were yet another level below this which would be the main concourse pedestrian level, so this is just a CGI rendering based on the architecture!
