Too bad Steve Lee didn't do this instead of 3985.  that engine is so of anti climatic now with a big boy on the horizion.

 

Steve Lee was asked that very question.  His answer is that a BB could only operate only on trackage in WY and UT.  That was then.  But 3985 can go to a lot more places than a BB.

 

BTW, does anybody know where a BB can go on the UP today under steam?

I keep on hearing people saying the bigboy was the biggest steam loco ever made.at 132..?? its the heaviest for sure..the allegheny had the most HP..As for length is PRR S1 at 140 feet and with 84"big driving wheels..

The Allegheny had 7000 boiler hp but sorry not the tractive effort.  That is what pulls trains not boiler hp.  The dm& ir had 140,000 lbs pulling power and big boy had 135,000 but the Allegheny had a little over 100,000 and was so hard on track it went a wooping 20 mph to keep track damage to a minimum.  The c&0 also sued lima for lying about weight on drivers.  It was not a success.  It is not even a good comparison for the big boy.  Lets compare successful engines.  As Gene Huddleston say in his book on the 2-6-6-6 after all the information was out "you decide if the c&0 got its moneys worth out of the engine.   Their 2-10-4 was their superior engine and it is compared in the same book.

Only?...Mmmhmm. 

 

UP's 4-8-8-4's would produce higher speeds, and could develop higher HP at higher speeds but they didn't have the starting drawbar pull of a 2100. The thing to remember is that these Y's had boilers the size of a big 4-8-4, and with compound operation it allowed them to squeeze that kind of performance out of it.  The 4000's had a humongous boiler with an appetite to match.  The higher speed is great but you need to start the train first.

  The real point is that each was designed to do a specific job for it's respective road and both performed admirably in that capacity.

Hold on just a minute there, Bucko.  All tractive effort does is start the train. The infamous Erie Triplex had monstrous amounts of tractive effort, but didn't have enough HORSEPOWER roll the train faster than about 10 mph or it would run out of steam.

 

It is HORSEPOWER that gets you over the road at speed. And the Lima-Built C&O Allegheny produced 7,498 DRAWBAR HORSEPOWER, far more than the Big Boy. That's REAL Horsepower, at the coupler, as measured by a dynamometer car behind the tender, not a calculated number.

hello OGR Webmaster and guys...........

 

It would be even LESS than 7,498 drawbar horsepower if measured BEHIND the tender coupler thus guessing about 7,000 H.P. @ tender coupler.  Its the tender coupler that is coupled to the freight cars behind so the horsepower should be measured there and could be called "net drawbar horsepower"

id thought id read some where its was 8000hp? other saying 6200 at the draw bar.. the PRR Q2 were 7987hp..measurements on the S1 and bigboy..bigboy..11'wide and 16' 2 1/2"high and 132'long...S1 10'7"wide and 16' 6"high and 140' 2 1/4"..Q2 11'4"wide and 16'5.5"high and 124 long.....If anyone can fill in the C&O alleghenys measurments..I couldnt find them..as for the largest steam loco ever built is the S1,but for production built bigboy is..model train mag there a post debaiting bigboy vs the allegheny..http://cs.trains.com/mrr/f/88/p/34200/436684.aspx

We apparently have a few folks that have been doing some "book learning", with no understanding of the REAL steam locomotive work environment, nor the physics involved.

 

1) The famous C&O H-8 was definitely NOT "unsuccessful"! Maybe the C&O never properly utilized the Lima Super Power 2-6-6-6 design to their fullest capabilities, instead of "just hauling coal".

 

2) The various eastern coal roads, i.e. C&O, B&O, and N&W for example, all had EXCELLENT supplies of VERY HIGH BTU coal as fuel. Thus their furnace systems were properly designed FOR THAT FUEL! By comparison, the "poor Union Pacific" was relegated to burning southern Wyoming Hanna Coal, and thus need MUCH larger fireboxes and furnace system designs, on order to burn lower BTU coal. Thus, the 4000 class locomotives truly excelled at their DESIGNED service assignments, while burning that southern Wyoming fuel. As another comparison, look what the poor Northern Pacific had to burn, i.e. Montana Lignite! 

 

3) Trying to compare various wheel arrangements, total locomotive weights, and total locomotive lengths add nothing to a discussion of individual steam locomotive performance.

3985 is far from anti climatic. The Challengers are the steam engine that represents UP's peak of the steam age better then any other engine. The Big Boys were only used in Utah and Wyoming pretty much. Challengers were used system wide. The restoration of 3985 also was not really started by Lee is was started by a group of employees before Lee was manager of the historical fleet. There are 6-7 Big Boys left only 2 Challengers. Personally I think the 3985 is still the better choice. Big Boy makes a nice wow factor but in the end I bet they use it rarely. I think its much sadder 3985 gets neglected since the new manager came around.

Were they 10 years old when UP hired them?

Now there is a manager that has been smoking the good stuff!

 

Lets do the math on that statement:

 

1) The last steam operations on the UP were out of Cheyenne, WY in something like 1958? So the Los Angeles area would have been out of main line steam locomotives in, what no later than 1956/1957?

 

2) A "steam qualified" promoted Engineer, should have been roughly in his 40s, during the mid 1950s, probably able to hold an Extra Board spot. That would make is age TODAY, at least 995 to 98 YEARS OLD!!! Even allowing for the possibility that the man was in his 30s, during the mid-1950s, would still put him well past 80 YEARS OLD today!

 

3) Say the man was a Fireman in the mid-1950s, and he was in his 20s. That would STILL make him well past 70 YEARS OLD today!

 

 

Now, does that Superintendent honestly believe that the Union Pacific STILL has 70+ to 80+, to 90+ year old men employed? What with the Railroad Retirement policy change, some 8 to 10 years ago, allowing FULL retirement benefits at 60 years of age, with 30+ years of service, why would ANY man well over 70 years old STILL BE WORKING (even if the railroad allowed it)?

I thought the same thing when I read the article.  There's no way that could happen....By the way, I love the first picture of 844.

 

HOTWATER:  I'm with you: My first thought was "how old would those guys be now?"  The math wasn't adding up!

 

I am curious, how does any RR find mechanics (with steam engine knowledge) and engineers to operate any steam engine?  I watched a clip on youtube of 3985's engineer and was amazed.  He made it look easy!  Steam engines haven't been used forever, so where /how do they train people?

 

Anyway, look forward to the pictures!

The Navy still runs some steam ships. That would be a source of boiler trained young people.

Sorry, but Navy steam boiler operations are not even remotely close to a steam locomotive. Navy boilers really aren't that much different than stationary boilers in electrical power plants, since the load doesn't vary all that much, plus they are usually very high pressure water tube boilers. Steam locomotives have fire tube boilers in order to withstand the numerous, and drastic loading changes.

Better then nothing. There are alot of x navy guys working for UP. The training navy engineers get dose fit in with the railroad.

You may be right, but how many are there on the Steam Crew?

Not enough. The current steam crew only seems to have big goals. Hope what there doing ends up being a good thing. I personally would have preferd they just kept  the equipment they have maintained. I'm looking forward to seeing the Big boy and all but I like 3985 just fine.

In reality, the current manager can not maintain what he already had, i.e. the 3985 AND 844, let alone rebuild/overhaul the 4014! Anyone taking any bets that the 844 will NOT operate during 2014?
