What am I?

[M636C]

I guess it's my turn again! Are there only three of us participating regularly?

This locomotive is very widely modelled, but most models are not correct. The models are usually of an earlier standard locomotive! In fact more of the later locomotives were built, since very few "standard' locomotives were built. The 'real' locomotive has smaller driving wheels, and the cab is a different shape.

This subject is a fairly large and colorful passenger locomotive, and an example is preserved.

On this topic I only read in awe [bow] of the knowledge about locomotives you guys have !
I wish I could join in, but I think I have to study some more !
btw I love the pics you post so I can see where you were posting about !
thanks !

Southern Ms 2-8-2? Its based on a USRA light mike.

Right Road, correct comparison, but the wrong locomotive.

A passenger locomotive, around the same size as a mikado, painted green!

i say 2-6-2
i may be wrong but this is fun[:p][:p][:p]

I was hoping for a slightly more precise identification, but Joe is right.

The Southern Ps-4 was based on the USRA Heavy Pacific, but had smaller driving wheels, a shorter boiler and a larger cab (since it did not have to fit the limited profile of some Eastern roads that the USRA had to allow for).

Most models of the Southern Ps-4 use the USRA Heavy Pacific unchanged. This error is reasonably obvious, since the real cab had taller sides and a flatter cab roof. You don't have to take my word for it. Take a Rivarossi model into the Smithsonian and compare it with the real Ps-4 1401, which is conveniently kept there for comparison!

As far as I know, Southern didn't have any 2-6-2s. But AT&SF had lots of them, so I can forgive a BNSF fan supporting part of his heritage.

OK, another question before anybody else wakes up!

In a museum (not the Smithsonian) is preserved a locomotive that was never sold! This big steam locomotive, with a number of unusual features went direct from the builder to the museum (in the same major city). It operated as a demonstrator, but was never sold to a railroad. No other locomotive had the same combination of experimental features.

Hopefully, the name of the builder and the name of the museum will be enough as an answer.

Timkin 4 Aces?

No

In fact, "Four Aces" was sold to the Northern Pacific as number 2626, and was built for Timken, so was sold new by the builder. I don't think "Four Aces" survived, either, which is a pity. A good guess however!

A further few clues: The locomotive has the same number of axles as "Four Aces" but more driving wheels. It was not built by the same builder as "Four Aces". It has more cylinders than "Four Aces".

Baldwin 60000, an experimental 4-10-2.

Yes

I did ask for the museum as well (The Franklin Institute in Philadelphia).
Baldwin 60000 had a water tube firebox and was a three cylinder compound as well as having two sets of valve gear on the right side, one to drive the centre cylinder. I believe it has never been repainted from the lettering it carried when placed in the museum in 1932! It moves a short distance on track inside the museum pushed by an hydraulic ram mounted between the rails.

I'd recommend checking it out any time you are in Philadelphia. It isn't too far from the Amtrak station. While not a typical locomotive, it could probably be restored to service relatively easily if required.

I've had two questions in a row now - someone else have a go!

[sparkingbolt]

I'll try this,

I am the first successful loco of my type, I have a 2-4-2 wheel arrangement, 2 engines, and my drivers are rod connected. I am not a steam engine. I am not a deisel. I am in a museum. What am I?

[TrainFreak409]

I think I know what that is, I found a model of something sounding similar on eBay. It was black, and I think it mentioned ALCO, but I'm not sure exactly

[sparkingbolt]

Nope

[sparkingbolt]

I'll give more specifics but it's still hard

I have a 2-4-2 wheel arrangement, 2 small, 4 larger rod connected, and 2 small like a steam engine. But I'm not a steamer.
I Have 2 internal combustion engines.
I am not a diesel
I don't deliver my power to the axles via electric motors, nor hydraulic, but use mechanical drive.
My engines are what make me most noteworthy, but the mechanical drive to iron spoke wheels adds to it. Still, I am considdered the first successful loco of my type

I suppose by now either you know me or you don't.

[M636C]

There was a gas turbine locomotive of that form which I think was built for the US Army.

I don't have any references with me but I think it may have been built by Whitcomb or Davenport.

I'm not sure that a gas turbine can be called "internal combustion" because the combustion chambers are not "closed" at any stage, having a continuous flow of air through them.

That is a very good guess. I think I'll second that one.

[sparkingbolt]

Exellent call, M636C, You nailed it. It is a Davenport, and US Army owned, is now at the Museum of Transportation. See it at

http://www.museumoftransport.org/rails-4.htm and a close up from another angle at

http://www.northeast.railfan.net/images/usa1149.jpg

That a gas turbine is in fact an internal combustion engine can be seen at
http://www.infoplease.com/ce6/sci/A0825332.html
but I have to admit ya had me wondering if I was remembering my high school education on that subject correctly.
The fuels are burned and the motion is produced within the same unit; engine that is. This applies to rockets and jets too.

Anyway, isn't that a cool little locomotive? I tried recently to model it but couldn't get the mechanism I was using to work.
So it's your turn, Peter. Dan

[M636C]

An easy one

This locomotive was often just called the Big Locomotive. Only one was built because it was probably too big. Some claims make it the fastest steam locomotive in the world. It was at one stage lettered for an organisation, not its owning road. It had more weight on the carrying axles than on the driving wheels. Its frame casting was said to be the largest single casting ever made for any railroad.

Road Name and Wheel Arrangement for a correct answer! Road class and number optional.

i dont mean to be rude but try to figure out this one after the previous one is solved.

I am a diesel Locomotive.
only three of me were built.
two as B units and i was never massed produced
i was built for a RR company who wanted more powerful locomotives
my model was abondoned and left with no future

hint: my twin engines crank out 5,500 hp
what am i????

no
but close

i did have four monster trucks
And the DD35 had been used after its creation.

Of course, what else could it be!

I have a German book that claims it made 141 mph with an ICC inspector on board, during the war!
