note - The vast bulk of my massive Web presence (over 485 pages) had been hosted by AT&T's WorldNet service since 30 May 1996; they dropped WorldNet effective 31 Mar 2010 and I have been scrambling to transfer everything.  Everything's saved but all the links have to be changed, mostly by hand.  See my sbiii.com Transfer Page for any updates on this tedious process.

Internal Combustion Engines

In 1924, Ingersoll-Rand perfected the first commercially-successful railroad diesel engine (termed an "oil" engine then because "Diesel" was a German name and not popular after WWI).  The first locomotive to be equipped with the engine was sold by the consortium of ALCo-GE-IR (American Locomotive Co./General Electric/Ingersoll-Rand), a "boxcab" to the Central RR of New Jersey as their #1000 and the second, with two engines, to the Long Island RR as their #401.  The engines were six-cylinder, 300 HP, units.  Several such locomotives, including that first CNJ unit, still survive and a few are in operating condition.

I was surprised to learn on 07 Aug 2007 that two more such engines, albeit larger ones, also survive; the massive Yankee Fork Gold Dredge, all 988 tons of it sits near Stanley, in central Idaho, up the Yankee Fork of the Salmon River.  Built at a cost of $428,304 by the Bucyrus-Erie Company in 1940, and measuring 112 feet long and 54 feet wide, with a four-story superstructure that is 64 feet high (essentially a huge barge), it was powered by two 450-horsepower Ingersoll-Rand series S diesel engines which ran generators to power the dredging and ore crushing equipment.  Not only did the engines survive but they have SEVEN 10½" x 12" cylinders each (29,094¼ cu. in.!) and could still run IF some critical parts like manifolds for the starting air and distributors for the timing of the air could be located.   rev.gif (09 Aug 07)

Here is a photo of one of the engines, with its generator:

Can anyone out there please help locate the starting hardware?

Rich Allen, the manager of the Yankee Fork Gold Dredge (which is one of the few dredges in the lower 48 that you can take a tour on) responded nobly to my request for more pix, including the generators:

How I'd love to hear (and feel) them running!

There she is, under Rookie Point, about a mile SW of Custer and a half mile N of Bonanza, where Loon Fork Road meets Yankee Fork Road:   added (12 Jun 2015)

The Yankee Fork stream bed has been devastated for some five miles to the south, all the way down to Polecamp Flat.  Anything for a few ounces, eh?  For all that, she was not profitable, digging up 6,330,000 cubic yards in her 61 months of operating time ca. 1940-1942 and 1946-1952 and both earning and costing a million bucks.

BRIDGES - continued - In the same serious vein as my earlier bridge coverage on the first Sci-Tech page, here's a fabulous shot of a bridge repair truck my sister forwarded:   new (12 Jun 2015)
