Here's my LOTW offering:

The 2 new "vintage-used" serviced and operating Rock Island RR RF-16A "Sharks," now serving on the RETRO TYCO layout. Both shells are not that great "cosmetically," however, it wouldn't be Tyco without a little bit of "weathering."

A bit of "Joeufomania" this week. The top is the new Joeuf, untested as yet,
and the lower is a somewhat battered Joeuf, my first, that I picked up
in trade. That yellow strip is a piece of old packing tape used to hold
the rather over sized motor motor in its cradle (since removed, I used
Liquid Nails to prop up its aging mount). Chunky and solid, it
follows the pattern of early Tyco and Mantua, when things were built
to last.

One of the prototype D6100's was fitted with a "Deltic" Diesel engine.
What was remarkable about the Deltic, was that the pistons were
arranged on three sides so that when two opposing piston heads
came to top dead center, the compression phase, they ignited
the fuel by extreme pressure (akin to all diesel motors, in terms
of pressure). This arrangement did away with the need for a heavy
steel head.

Advantages of the engine included fuel efficiency and no need for
poppet valves, and such. I have no idea how reliable they were.
The use of marine engines in railroad applications in post war
American locomotive applications, such as by Baldwin (I think)
was a notorious failure.

You may be thinking of Fairbanks Morse. They had an opposed piston diesel engine that worked very well in submarines but had troubles in locomotives.

That is precisely the one I am thinking of. It failed miserably in demostrator
tests on different railroads.

the problem with opposed piston engines of any type is not so much their reliability, but the fact that any engine work requires the removal of at least one crankshaft. This is an expensive and time consuming process and as a result these locomotives, at least in the USA, were given lower priority for repairs than locomotives like EMD that could be put back in service quickly. Railroads keep figures on maintainence costs for each type of locomotive, and locomotives that are cheaper to repair are preferred.

Interesting info, jward. This is the one I was thinking of, it was an Alco using a
surplus post WWII submarine diesel.

Chops, that photo is of the Black Maria demonstrator. there were 3 units, am A-B-A set. I don't believe those used a submarine engine, rather they were the only application of the Alco 241 engine. During WW2, alco was forbidden from building road diesels but was allowed to build this demonstrator set. It was the prototype for the FA1, which used the updated 244 engine. Alco used the demonstrator to work the bugs out of the basic design, but couldn't put it into production until the wartime restrictions were lifted.

As a bit of Alco trivia, the first customer for the FGA1 was the new Gulf, Mobile & Ohio, itself the result of a recent merger. The GM&O Fa1s were unique in that they had the headllight mounted lower on the nose so that the headlight grille didn't interfere with the smooth curve on top of the nose. Subsequent FAs and PAs had the headlight moved higher, resulting in the familiar Alco look that the model versions have.

Note that the black marias have a look similar to the DL109, which Alco was allowed to produce for New Haven during the war, This is just speculation on my part, but I suspect the fact that the DL109s used the same 539 engine as the switchers Alco was allowed to produce during the war may have had something to do with this notable exception to the ban on any builder but EMD producing road diesels during the war.

jward, I am again in your debt for your thoughtful insights.

Mike, you continue to amaze with your beautiful and unique pieces.

Are you possibly thinking of the Ingalls engine?

Too much coffee and too much time! I need to get a job.
This is the one, but it didn't have an opposed diesel engine.
I do recall that the original article, I read some years back,
in either Trains or Classic Trains, stated that it was a surplus
submarine engine- but then my CRS syndrome kicks in.
Noteworthy in this site, it was scrapped two years after
its introduction, having a big motor fail on the B&A.

And to Microbusss: I saw them first! And how come you
not posting pics?? You got more cool stuffs than all of
us combined!

My LOTW is the Fish Hook and Mussentuchit RR number 82. It's a very old Mantua 0-4-0. Originally it had the die cast tender, but that had zinc pest, so I replaced it with a newer, plastic one. I bought it to cannibalize for parts, but much of it was subtly incompatible with newer engines. For example, the gears did not mesh with newer ones, so the motor can not be swapped with other locomotives without changing the worm on the shaft. The previous owner did some elaborate work on detailing, so except for some changes to electrical pickup, I use the engine as is and have painted and lettered it for the FH&M.

My loco this week is a Mantua Shark B unit. This is a cast metal unit to go with my A unit. Took a
while to find it, but I did. This is a powered unit using a MU-1 motor.
