Wow. Thanks for that. Like some vision of industrial hell.

Watching the valve gear on the one engine where they showed it up close, I'm pretty sure they weren't working it very hard. The intake valve was barely getting popped open before dropping off of the latch.

I see too that at least one of the engines was reversible. I haven't seen that on a Corliss before. Probably to back it down when some wretch gets caught in the gears!

And I got a kick out of the hunk of scrap metal hanging on one of the damper pot rods. A fine mixture of great engines being kept in service by all sorts of low cunning.

Thanks for the video, CB. Looking at those Corliss valve gears is mesmerizing.

I noticed something very unusual on such a large power plant, something that looks very much alike a reversing gear.
