UP Big Boy 4014 and 844 at Ogden, UT! by 844steamtrain See my videos! www.youtube.com/user/844steamtrain prrt1steamlocomotivetrust.org/ - Please help fund the T-1 Trust! They are a wonderful organization, building an advanced new 4-4-4-4 T-1 steam locomotive from scratch! One of the most viewed UP Big Boy train photos on Flickr! Union Pacific Big Boy 4014; the world's largest, heaviest and most powerful steam locomotive, is now fully restored to operation! Here we see 4014 and 844 at the Spike 150 celebration in Ogden, UT! It was said for years that this was impossible. It's too big, too impractical, too expensive, too heavy, can't burn oil, etc. Now we have our answer; it IS possible! One question still remains. Can 4014 dethrone the Flying Scotsman in popularity? Only time will tell ;) If you enjoy my photos, fee free to like, share and thanks for viewing! https://flic.kr/p/S6jiJZ
