An engine like this is a work of art. And a rugged heavy duty piece of equipment too. The response to this icon of the industrial age is phenomenal. People understand the size power and refined sophistication of fully mature steam technology. Not only is this locomotive a beautiful sight and a wonder to behold, it is useful too.
@@MountainAdventures1 Strange, when I googled they only offered Pa & Va, no Co?? Why didnt they bring 4014 on east? Wasnt there any "road reciprocity"? LOL If Pa I WOULDA BEEN THERE WITH BELLS ON!!
American Industrial beauty personified in living form. God it's a monster on rails. I wonder how much pressure pounds per sq inch does it takes to move the pistions that turn the wheels.
boiler pressure is 300 psi. google the specs, fascinating. Really beautiful action.at 9:20 slow the speed down to .75 and watch the side gear.. (the front cyl has a leaking packing gland). That "rocking" curved member is what opens and closes the valve. If the member it moves is below the pivot the engine moves forward. If its above the pivot it puts the loco in reverse. How far it is from the pivot determines how far open the valve is pulled admitting more or less steam into the cyl (kinda like the gas pedal in your car),. Watching the BigBoy really rings this old B&O guys chimes!!!
@@frederickwise5238 Thanks for the fantastic information! It was clear that there was some kind of seal leak in that front cylinder. I also thought it was interesting that the engineer vented the steam exhaust directly (starting at 6:40), instead of up through the stack, can't say I've ever seen that done before. it was neat to see the steam swapping sides on the cylinder. I also got a kick out of the fact that it wasn't just being paraded around with a couple coaches, it was actually pulling a line of freight cars.
@@MountainAdventures1 Im an old B&O machinist. Did some packing glands in my apprentice ship. At 6:40 the loco had been sitting., Any steam which had remained in the cy would have condensed into WATER. That water is incompressible and had he started moving without draining any and all from both ends of the cylinder it could.. A) blow the head off the front or B) wreck the rod and running gear on the back..Somewhere in my files I have a photo of a N.Y..C. Hudson loco where the whole side rod assembly was torn off when a valve gear lever railed AT SPEED.!!! The piston rod was bent, the connecting rod was bent like a pretzel and ripped off and had flailed along the track side till they could get stopped. (ripped up a lot of tie ends and scattered gravel for more than half a mile. That water and steam had to be vented DOWN out of the bottom of both ends of all cylinderss. to carry water out. To replace the packing gland is a several day job. ALL of the side gear has to be removed.and that end of the cylinder removed. Pacxking goes in from the inside. - then all has to go back on. Yakes cranes, men and time. LOL
@@MountainAdventures1 Re "the line of freight cars. In comparison that was kinda like a Cadillac pulling a kid on a skateboard. That loco used to pull 5 mile long fully loaded ore cars up the Wasatch mountains. That's what it was designed for and its original "name'. "BIG BOY" came from a comment by a man at the loco works. During WWII it and its brothers pulled miles and miles of raw materials back and forth to factories and miles and miles of men and finished equipment to shipping ports on both coasts and the Gulf. BTW in 1998, I hade the pleasure of shaking hands with a man who had been engineer on both a Challenger 4664 and a BigBoy 4884. Met him as my son and I were passing thru Memphis on our way to Tenn.. I didnt wash that hand for some time after. LOL.
@@MountainAdventures1 Because of your interest in th Big Boy I tho you might like this video. It explains in great detail about all of the valve gear. in slow motion. "Walschaerts valve gear" ua-cam.com/video/b7NABUkyGok/v-deo.html

woah big fan ace
Strasburg what? The only Strasburg I find are Pa and Va and I know it didnt come this far east.
That would be Strasburg Colorado...
