Thank you Union pacific for bringing back this awesome peace of railroad history cant wait to see it for my self one day!!

Thank you, Union Pacific, for bringing back one of the most iconic steam locomotives ever. Welcome back UP 4014.

Well done Yanks, just bloody well done. UP and all the team should stand proud both of their work and the service they have done for your country. Take a bow. I send you greetings and salutations from this side of the pond in UK

I drove from NJ to St. Louis to see this for a minute and it was worth every second driving

The Union Pacific has never changed its name - it has been the Union Pacific since its inception. Union Pacific knows it helped to build a nation, and that today, it helps sustain it. Unlike some other railroads, Union Pacific has never forgotten or ignored its own history. UP embraces community, railfans, and friends - rather than repulse or push them away. UP is friendliness, class, power, glory, and strength. UP is America. Thank you Union Pacific!

A testament to the skill of AMERICAN tradesman and a company willing to invest in those employees. WELL DONE Union Pacific!

She looks better then new, simply amazing. The steam community is forever grateful to you (U.P) for not only seeing the value of these historic machines but continuing to support every aspect of the heritage fleet. Long Live U.P Steam, and thank you from the great white north eh.

Thank you Union Pacific for restoring the mighty locomotive. Thank you.

Bless you Union Pacific. I'm sitting in Australia watching this with tears in my eyes. Welcome back 4014.

Thank you Union Pacific for bringing back the legend the big boy

Honestly never thought I'd see the day a Big Boy would return to steam, conisering the huge costs involved. Well done to all. Can't wait to come to the states and see it run.

OMG SHES FINALLY DONE!!! BEAUTIFUL!!

I never had a thought that this would ever happen, not only getting one in running condition but fully restoring one is absolutely amazing! Thank you to Union Pacific.

Literally the best railroad company

So happy it’s restored! Well done UP!

What a great company Union Pacific. To restore this wonderful icon of American history shows you care about your history and your countries heritage. People from around the world are very grateful to Union Pacific, long may you prosper. Thank you from the UK.

I wish to thank the Union Pacific for allowing, suppotting, compleatting, operating and maintaining of the Union Pacific Locomotive 4014 and the Union Pacific Locomotive 844. I hope to see in the near future the Union Pacific 3985 back in full operating condition. I would love to see Union Pacific 4014 doing what he was built for taking a freight train between from Cheyenne to Ogden.

Thanks you Union Pacific for being the greatest and most influential railroad in the US, great job guys

I wish my dad was here to see this he loved steam engines.

What words can begin to explain how America feels regarding the return of BIG BOY! Everything GREAT to the Union Pacific and the Steam Crew.

Sometimes even the most serious of railroad executives has to go out and engage in the sheer delight of playing with the trains. What a delight!

I plan on bringing my family (all 5 of us), from Australia to see and ride on a rolling piece of history.

My Father instilled in us a great love of all things rail, particularly steam. I remember the UP calendar arriving every year. Dad would have absolutely loved this! Thanks UP!!!

I don't know what to say. She's glorious. Salute to Ed Dickens, the entire UP steam team, and Union Pacific, the greatest railroad ever. AWESOME!!

And that's why your number 1 in the world. No one bigger! Go big train! GO U.P.!

Thank you Union Pacific. I can't express how much respect I have for the steam crew. Congratulations!

Dear Mr. Fritz...thank you for supporting the effort but please remember this effort will be remembered long after you and I are gone. This is American history! Few have had this opportunity.

Something I've wanted to see since I was a kid. Thank you, UP.

I thought that I had missed the Golden Age of Steam. To see a Big Boy fully restored reassures me that it’s a damn great time to be alive. Thank you, Union Pacific, for never giving up on the people of the United States of America

tears of joy as i see the old girl back on the rails

Thank you random team from France, for restoration on Big Boy 4014!

She's DONE!!!!! How awesome!!! Thank you to Union Pacific for taking on this enormous task, and bringing a piece of American History back to life. Can't wait to ride her!

What a beautiful sight seeing a double header between the 4014 and the 844

That whistle sends chills up and down the spine when it sounds off! Great!

I cannot say anything that has not already been said, but I must say Thank You! :)

Who would ever have thought we would see railroad history on the rails again. Incredible!!

Return of a giant and a piece of American history. Thank you Union Pacific.

1:01 That's me and my brother! I'm on the right and he's on the left. We chased it all day to it's first overnight stop, and it was a lot of fun!

I've waited for this moment for a *VERY* long time. Thank you to all the men and women who put their heart and soul into making this beast of a machine rule the rails once more.

Thank you Union Pacific, I have been a fan of your work since I was 5 years of age, and this is a dream come true.

Congratulations Union Pacific! You did good bringing the Big Boy back from the dustbin of history. This behemoth's resurrection and return to the rails befits our nation's grand sesquicentennial celebration in Utah to commemorate the Golden Spike ceremony that marked America's first transcontinental railroad. Thanks for sharing the Big Boy with all of America in this celebration. -from Tom Pilling

Return of the King! Well done UP and to all those incredible people who made it possible to bring this magnificent beast back to life! A U.K Rail Enthusiast rail enthusiast

What an amazing locomotive and what a dedicated team to have brought it to life. Union Pacific, thank you so very much. This locomotive is one of many that sparked my interest in steam and it is so nice to see it back.

Outstanding work!

Love from Spain 🇪🇸 Total Respect for what you did here.. just ‘awesome’.... USA has its issues.. glad to see honoring your past hasn’t fallen foul of the beancounters.. this at least, is a ‘pure’ act & i love you for it.

YOU DID IT Union Pacific you've done well for getting the job done...and I can't wait till Big Boy comes to California in person

When the COVID news gets too much I rewatch Big Boy UP videos to boost my spirits. Going to the past, touching on nostalgia, reconstructing the past using Big Boy steel and steam, gives me the steel to get through COVID. Health and strength to you all rail fans ...

I was so excited to hear the news about the restoration 5 years ago, I can't believe its finally complete!!!

Brings a tear to my eye. I feel a weird connection with this machine, its power has always fascinated me since I was a child. Thank you Union Pacific, greetings from Italy.

This is the most glorious moment in Railroad history. Thank you Ed Dickens, Jr. for your amazing contributions to our steam program! May your leadership continue to grow for many years to come! Now we just need to bring 3985 back to life.

Thank you guys, seriously, thank you for rebuilding a huge part of American History.

Thank you Union Pacific for making this possible!!!!

This is history. Thank you

Thank you so much Union Pacific for bringing this bad boy back to life! I appreciate it so much!

Americans have always loved and respected the biggest, fastest and heaviest mechanical machines in the world, and the Big Boy more than meets those criteria in every way. That's why it is so special that the Union Pacific rebuilt this huge baby from an era gone by, so that those today do not miss out on seeing and hearing this historical piece of American railroading. Thank you Union Pacific for your efforts in keeping American railroad history in the foreground. Great job!

Looking back this is one of the most important pieces of American history even though it’s in the modern generation. We will never forget this. Welcome back big boy

2:19 Steam engines and Wind Turbines. Truly the Alpha and Omega of energy.

Steam engines are a piece of beautiful mechanical engineering and all that can be rescued, restored need to be. Thanks you Union Pacific for all the history brought back for all too see.

Welcome back the monarch of the railway!

God she is beautiful

Truly amazing! You guys did an outstanding job on bringing 4014 back. As a Pennsylvanian, I hope one day I’ll be able to fly out to Cheyenne to see the machine myself.

The golden age of railroading bought to life

Well done folks, well done! Congrats to the UP Steam Shop for achieving this monumental goal.

Thank you Union Pacific for bringing back this historical locomotive back to life. People in all ages gathered from far and near to watch this historical moment to see a Big Boy running on it's own power for the first time in almost 60 years! Union Pacific never forget that the Big Boy helped build America after World War 2, and that's why Union Pacific should stand proud for their motto - Building America!

UP Joe Passentino is smiling down from heaven and no doubt jumping for joy.

Thank you union pacific so much for bringing back to life the most beautiful magnificent giant of all time and my childhood dream the big boy wich represents the beauty of all steam engine. Thank you UP for taking your time to make our dream.

Thank you! Bringing this back brings back a tangible piece of history to our family. My grandfather worked as a fireman on these locomotives going from Ogden, UT to Green River, WY. He died before I was born and there is little left that we have from him. This is something special to us, his descendants. We’re very appreciative of the decision and work that went into restoring this beast.

Amazing work union pacific🎉

bring it east!!! i'll buy two tickets for me and my excitement!!!!

What a moment! I wish I could have been there. Thanks to UP for giving Big Boy back to us!

How time flies. I still remember when this project was announced, and it's finally done. An incredible job by the restoration team, and kudos to UP for willing and standing by their promise 👏

Congratulations and Thank You U.P. ! You’re a class act in the Class 1 world. The spirits of all the men who’ve worked and ran UP steam are smiling from above.

Thank you, UP, for recognizing that you have an irreplaceable piece of history here, and for restoring it and sharing it with the world.

DAMN, that is a gorgeous piece of workmanship. I cant wait until it comes through Jefferson City, MO.

Thank you Union Pacific for bringing the big boy back to life once again and thank the lord for making it possible

My goodness gracious, what a wonderful job the UP team has done in restoring this beautiful locomotive! Congratulations!

I love her soooo much! Thank you for bringing her back to life!

One nut and one bolt at a time - sheet metal; ingenuity -- and she's Up and Running!!!!!

Thank you Union Pacific for bringing this incredible piece of history back to life.

You brought the big boy back, and i'm damn sure he'll be hauling cargo across the lines once again.

Union pacific I love you guys and so so so happy to see a big boy run before

UNION PACIFIC rocks. ***** Nice video. Thank you. Greatings from 🇭🇺Hungary. Also from our Big 424 BULL. Steam locomotive.

Amazing - Thanks for investing in this, great corporate foresight

Now I have a reason to visit the U.S from Australia 😁 long live 4014

This Aircraft Engineer is very impressed! WELL DONE!

Well done UP! Thank you for taking the time and effort to restore this icon. My hat off to the entire steam shop crew for this monumental feat. I hope you post the system tour schedule, I'm NOT missing Big Boy when it comes to Iowa.

Thank Union Pacific for taking the initiative to start this amazing project. Next I would like to thank every hand that was laid on hey everybody this Behemoth piece of metal, bringing it back to the fully operational unit we can see today. Thanks to all of you, and thank you for not letting steam die. I was born about the time that steam died out, and it's good to see this being revived! Good work everybody! And again, congratulations

What a beautiful thing to see happening in American soil! There’s no words to express the joy such an initiative brings in! Congratulations for the awesome job!

So awesome

About 25 years ago, I heard a UP Public Relations spokesperson call the Challenger to Atomic Weapons of Public Relations. UP, you now have the Hydrogen Bomb. Thank you for doing this UP; preserving your corporate heritage, and all our American heritage. Well Done.

Thank you, UP, for your willingness to invest the time, money and effort to bring this piece of American history back to life! You guys rock!! 👍👍

Wow, absolute respect for everyone involved in bringing this grand locomotive back to life.

childhood dream... realized! Amazing work guys!

Thank you UP for your continued commitment to history and the communities you serve, I will enjoy seeing the heritage crew bring him through the midwest, Please everyone enjoy this gift with care and respect to the Union Pacifics commitment to safety and Security.

What a tremendous and outstanding accomplishment! What a class act ! Thank You Union Pacific for giving your Country something to rally around , to get excited about and something for everyone to enjoy and believe in . When the Big Boy comes to a town near me I plan to experience this magnificent machine for myself .

I’m so sad I will never see this beast in real life because I live all the way over in Australia but I thank you so much for bringing this giant, gargantuan piece of absolute amazing material back on the railway to transport passengers, freight and memories. I’m hoping this engine doesn’t break down for about at least two decades to give me enough time to move out because I’m 11 right now and want go to America to view this gargantuan beast for myself

You have done an incredible job on that absolute giant of a locomotive :) It's truly awesome to see something like this back on the rails again! It's absolutely breathtaking!

The fact you managed to bring back the titanic of all steam trains is amazing, congratulations Union Pacific. I may fly over to watch the train one day.

Please come to Seattle!!!

To the Union Pacific Railroad, Ed Dickens, and countless people who worked on the Big Boy and the other steam locomotives in their livery, thank you for bringing the Big Boy back to life, I said to myself many years ago how amazing it would be to see a Big Boy thunder down the tracks some day, I guess I never really thought it would happen and you all made it possible for everyone to enjoy once again. Steam locomotives are an amazing part of our country's history and for you all to have so many of them that are preserved in running condition is such a great testament to you and the people you have working there that have a huge passion for preserving them, I'm quite sure that it's not really profitable to spend tons time and tons of money on the steam program but you all have done an excellent job of keeping them alive for generations to come when most other railroads have given up on any type of steam program, I have said to my self that I almost wish you all would get the J611 and take her out to the mid west and make her a part of your amazing steam program so she could stretch her legs more often, the Queen of steam would be in the same company as the King of steam but maybe things will change for the better for her, she's going to Strasburg for the fall and maybe next year she will be run even more, thanks for all of your hard work and dedication to the steam locomotives you have cared for and loved so much and made it possible for so many people of all generations and from all over the world to enjoy once again.
