Big Boy VS Challenger - Classic Toy Trains Magazine

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,
