Splendid news for steam fans in the west! The restoration paid off!

what's that weird contraption on the smokestack? I see it in historic photos from the Santa Fe days so it's definitely historically accurate - I just have no clue what it is or what it does?

Extendable smokestack that could be raised at the engineer's control.

That's really cool - is the 2926 the only restored locomotive in the USA with this feature?

Maybe ATSF 3463 still has one?

ATSF № 3463 does indeed have a stack extender, but she is not being restored to operation.

I believe UP № 4014 briefly wore a collapsible clamshell extender last year.

I wonder why the 3751 seems to lack hers now. She carried various versions of extendable stacks during her career and carried the last one throughout her static display life.
