So glad she has her original whistle back on. That roar just truly fits this massive titan, just blasts right through your chest.

Glad to see that big boy 4014 had at least one operating session during 2022.

8:43 that inspection car is cool as s###. Lights to light up the track at night. Would be incredible to ride in.

In the closest shots, 4015 was pushing to keep the spectators from getting "steam cleaned".

Is that the steamer from the galaxy railways

[@JoshuaRicamonte-cr4oh]

Who is more powerful Is it a steam train Or a diesel train

[@royshashibrock3990]

I don't know enough about trains, but I can't understand why the diesel locomotive is necessary. It is always there and it is clearly running. So how much of the motive power of the train is being supplied by the steam locomotive 4014?

[@darlenemassey6161]

All of it... the diesel is there for dynamic breaking required for running on the mainline and for communication services. It was used once I think last year when the Big Boy was on an excursion and they could not get water so the diesel powered the train until the next depot with water service.

[@justahillbilly7777]

The diesel is also there to supply the needed Positive Train Control. The 4014 has a monitor for it in its cab, but it’s the diesel that supplies the bulk of the necessary computer gadgetry to make it all work. If you look close enough, you can see a gray cable along the fireman’s side of the tender and water tenders that connects to the diesel, which is for the PTC. Pretty neat how Uncle Pete worked it all out, though I do hope they keep going and take it one step further and eventually have it worked out to where the 4014 and 844 have their own self contained and independent PTC systems, therefore negating the need to use a trailing diesel to supply the necessary computer gadgetry. UP did state in an article talking about the fitting of PTC to the 4014 that such a system was the ultimate end goal, but I’ve not heard much about it since then.

[@spectrackular]

At the end of the day, Big Boy 4014 is around 80 years old. May need a little assistance here and there.

[@75Marvell75]

Does this locomotive carry anything else besides these wagons?
