I am curious if anyone has ever made a list of the biggest preserved steam by type in the United States. This list would be of observable existing steam. Big Boys, Alleghenies and ATSF 2900's are excluded, Let's see your lists!!! Biggest is by engine weight only.

https://www.steamlocomotive.com/ is a great place to start. That's what I use to find out similar bits of information, and it's usually kept up to date very well.
