Big Boy VS Challenger

[aflyer]

Can anyone tell me if the Challenger and the big boy are both the same locomotive with just different wheel configurations?

4-6-6-4 VS 4-8-8-4

Thank you,

George

The Challenger, Big Boy, and Allegheny - while they look similiar are very much different engines.

Great reference material. If the OP was asking about the Flyonel models the answer is they are different, inside and out. They also have different features and perform differently. The Challenger was Lionel's first true 1/64 scale steam engine. The Big Boy was an S gauge adaptation of an undersized O gauge engine. It appears to be about 1/60 scale. In my opinion the Big Boy is the better performing engine but it essential that the mods and adjustments described on Carl Tuveson's web site be completed.

Thank you for the information links on the real  Big Boys, VS Challengers.

As Tom suggested I am looking for information on the Flyonel models.  The Lionel data lists them as virtually the same size, however I had read previously that the Challenger was all new tooling, and built more to 1/64 scale.

I will go check out Carl Tuvesons information.

Thank you again,

The Challenger and the Big Boy are not the same locomotive.  However, almost every major element of the Big Boy is similar to that of the Challenger, but bigger.  The Big Boy can be fairly characterized as a "super-sized" Challenger.

Bob,

Thank you for that information. I have done more reading and it seems the Challenger is a new and more better scaled version.

I find it interesting that all of the Lionel advertisign list them both at about 25" in length.

Thanks again,

There's been a bit of discussion about  UP 4014 being restored on the "Trains"  website Forum.  Making a long story short things have gone quiet on 4014.  No-ones saying anything, no-one knows anything.  "All Quiet On The Western Front"  as it were.

 All sortsa interesting stuff on the "Trains"  site.  You'll find it interesting.
