    Not only doing the work by himself but also doing some nice freight work... and with a caboose! Love it! BIG BOY is making me nostalgic yet again! I understand the purpose for the diesel in prior runs and still love diesels, don't get me wrong! Love all trains.

    CPR 2816 is an elegant engine ... but Big Boy 4014 looks badass!!!
  • @THOMAS81Z
    still cant belive we get to see a big boy heading west leaving the yard under the bridge in 2024 ,not 1954!!!

    I was in that blue ford ranger pacing it when it was going up the grade at Speer, I ended up going down the access road a lil bit and ran into a UP officer who actually gave me permission to continue chasing big boy up track 3 on the access roads! Once in a life time thing getting to see that.

    Let's take a moment to give props to that first or second hopper with the flat spot getting the chance to do what most of us never will.

    Anyone else notice the dynamo’s are higher pitched and quieter even though there’s now 3?
  • @robertrussell2166
    People are getting the wrong idea about 4014 operating without a diesel. This was to test the PTC so she needed to operate alone. On the coming West Coast trip at least one diesel will still be used to save the extremely expensive braking system on the Big Boy. Parts are no longer available so brake parts need to be custom fabricated which is expensive. The diesel takes the braking strain off the Big Boy

    I assume the ground was shaking at Speer because Big Boy 4014 thundered on through with his weight? :3

    It’s amazing that UP is the only company that has a steam locomotive is operation today. The Big Boy must have a lot of support to keep it running
