According to the guage in that video, it was only at half of its operating pressure.

Correct, however,,,,,,,sooner or later they MUST exceed 300psi in order to test/set the three safety valves, per FRA regulations.

Thanks for the info, I was also wondering about that.
Once they've brought the locomotive to full operating pressure, does it need to be inspected again?
When the safety valves are doing their job, are they, "popping off"?

Yes.
Most folks think that the "safety valves" are to prevent the boiler from exploding. That is NOT true. The safety valve/safety valves provide an audible warning that the Fireman is exceeding the maximum working pressure of the boiler, and thus is potentially over stressing the running gear machinery. Thus, the purpose of the safety valve/safety valves are to limit the horsepower of the machinery. Throughout history, the safety valve/safety valves have NEVER prevented a catastrophic boiler explosion due to low water! Anyone who thinks that those 2, 3, or 4 3" to 4" diameter holes in the top of the boiler are capable of preventing a massive explosion, are dreaming.
Time to admit that Ed does know what he is doing and stop negative comments about the crew.
Are those straps around the boiler to the dome only temporary until it gets properly attached?
Good to see her out and moving. Can't wait till they put more pressure into that boiler and have her moving without a diesel behind her!

Sorry, but the current manager does NOT know what he's doing! Many members of the current crew do. That is why additional contracted workers came in to complete the job. Also, 844 STILL hasn't made a successful main line test trip yet.
Excellent
With all due respect Jack, I can understand you having an axe to grind against him and his show, but please try to keep the same argument against him out of this post. I posted this video and article to show to all of the UP steam fans that regardless of the dis-function the 844 is back and hopefully steaming again for many years with or without Ed.

If I may, Jack wasn't blindly grinding an axe. Someone else posted something that demanded a response, where seeing a locomotive run would stop the negative comments against Dickens.
I'm sure that if someone hadn't posted something like that in the first place as bait, this thread could have gone without any comments against Dickens.
On another note, I'm still cautiously optimistic. I've followed Flying Scotsman's trials in getting back to the main line to know that sometimes an early steam test isn't the last word in getting her up and running completely!

I think you are confusing the issue.
A boiler explosion is not necessarily caused by an "overpressure". It can be caused by an undesired opening (ex. - crack) in the boiler allowing the steam to suddenly lose pressure by venting to the atmosphere where it immediately expands causing the explosion.

Eddie,
I am fully aware he's not blindly doing so. And in fact I'm one of his supporters on here that believe he deserves every right to speak his mind. He's contributed at lot to the program and is passionate about his work and most of all wants to see it succeed.
The only point I'm trying to make is to look at this situation in an optimistic light and not a pessimistic one. It is easy to look for the negatives and sometimes when it comes to this topic that's all we hear.

Yes ..... lets not give up hope, everyone!! There is still plenty of time left for the UP Steam Program to fail before Frontier Days.
I know of a museum or two that keeps their operable steam tractors un-jacketed for ease of inspection and certification. Those only run two or three times a year, though.
For 844 to be at this level of operation compared to previous information is an accomplishment, for sure. There must have been a large surge in manpower and resources very recently.
Nice to hear a UP steamboat whistle again........

The white you see on 844 is insulation that is ready to be covered by the sheet metal.
I really know nothing about this project. I am passionate about letting all opinions have a voice. Trying to exclude folks who do not agree with you from a conversation seems to me to be a very bad idea.
Opinion.
How serendipitous that the 844 comes back to life and the Lionel models shipped about the same time

And yet, it's very common online anyway...
