Union Pacific 4014 @ 75mph Time lapse

3x time lapse of May 7, 2014 footage UP4014 ran at 25 mph on the return so 258 seconds reduced to 86 seconds would be equalivant to 75mph. If all goes well in a few years this will be for real.

This is entirely possible as top speed on the Big Boys was 80mph.

I just ran the math for 4014 moving at 75MPH. It's 31, 000, 00 joules of energy. Or about the energy a 1 KG piece of anthracite coal has...

What an unbelievable, beautiful, massive piece of machinery. Built by engineers, craftsmen and NO computers. Need I say more. THANKS TO ALL AT UNION PACIFIC!

[bigtex]

Love seeing what a Big Boy at top speed would actually look like! Also incredible to think about thousands and thousands of pounds of side rods and linkage flinging around like that

[limited]

Interesting I didn't think they'd gone this fast with 4014 at least not yet. Did UP ever run them this fast when they were in revenue service?

[basedjorts]

That was pretty cool. I can't wait to see this happen for real.

[RailFoxMedia]

Gosh damn! I’m surprised it was able to make to Cheyenne after surviving all of that

[MrHS]

😅Thanks for the ride, I thought it looked brutally fast 3x makes sense thumb up. 😊

[EricR]

Haha! That's great!
I'd like to see the 2x -- that's probably a more realistic expectation.

[anasiacameronelijahedcpndc]

4014 will travel 75mph after it's restoration and it would triple head too

[gryphon]

Set the playback speed to 2x...this is how black holes are made...

[MorrowidAddic]

Can't wait to see this beast go that fast on its own!

[strikesolo]

I thought this Big boy was desgin to run at 60mph .-. I didn't know she can run this fast

[davidng]

Still running rather slower than 75 to this day.

[jacksalvin]

After static display at the Fairgrounds.

[shininghappyperson]

All the videos of 844 running at such speeds would have made this totally believable if it wasn't stated in the info that it was a time lapse. 

[vonmillardmanalastas]

Believe it or not, all Union Pacific Big Boys have a Top Speed of 80MPH without pulling anything.

[Einsteindks]

Imagine all the weight being thrown around, throughout the drivetrain, at those speeds!

[johnnyhernandez]

how can this be possible the big boy has not been back in service for over 6 years and this video was made six years ago

[sharifhajirol]

No 110 mph yeah that's the speed of the big boy 4014 and 844 should 115 mph
