Re: Polymer Corp., Ltd / Polysar tank cars

I should preface this by saying I'm a small-molecule organic chemist
not a polymer chemist. But a colleague of mine *is* a polymer chemist
& I'll check this w/him. But, he's a Dean & subject to capture by
bureaucrats, so no promises on timing.

That said: the metal inside of an un-lined tank car is a reducing
environment, chemically; which can cause polymerization.
(Polymerization can be caused by reducing agents, oxidizing agents,
acids, free radicals: almost anything reactive.) I'm not sure, but I
suspect the word "latex" may be used two different ways: to mean a
latex polymer, like latex gloves, or to mean a latex "living" polymer
like what Mr. Valoczy describes. But at a quick guess, if one lined a
tank car with a latex polymer, I don't think it would react with
a "living" latex, whereas a metal tank might.

you're the materials guy, and you have a better chance of knowing
than I do . . .

If it'd make a difference... the latices in question would probably
be things like unfinished (i.e., uncoagulated) styrene-butadiene or
other synthetic rubbers. The liquid output after the ingredients
(styrene and butadiene for SB rubber, aka GR-S or Buna-S) are co-
polymerized (using other chemicals as catalysts, emulsifiers and
retardants) is called a latex; the latex is then fed into another
tank, where it's mixed with brine and sulphuric acid to make it
coagulate into little flakes of solidified rubber that's then baled
and shipped off in 40lb bales (likely the contents of the UP boxcar
I saw in another photo of the Polymer Corp. plant).

Now, whether this latex described above would be corrosive or
otherwise dangerous to put into an unlined tank car, I don't
know... perhaps someone who understands polymer chemistry a bit
more could answer that.

A few of you contacted me re: Yahoo stripping the photo attachments from a
recent product announcement. The web page has since been created .. there
are a couple of code typos that need to be fixed but the primary reason for
sending this email is to allow y'all to view the proto pix and pricing info.



Click on either image to look at an enlarged version. Credit Larry Goolsby
for the "block font" photo and the SRHA, Inc.'s Archives for the "roman
font" view taken at Spencer Shops prior to car being released for revenue
service.



Due to problems encountered with waffle box verbal/email reservations not
being honored, I am requiring a non-refundable 50% deposit for all wood rack
orders. Since this is a done-deal kit, available by early January '09, you
won't lose your deposit or be delayed in getting your kit(s) as has
sometimes occurred with other manufacturers over the years.



Here is the web page link:

Extreme Trains this Tuesday on the History Channel

lnbill <bwelch@...>
 

I note that on the History Channel's series "Extreme Trains" that next
Tuesday's episode features a contemporary reefer train. The
description says it also covers the competition between truck and
trains in the 1950's. These histroical retrospective often feature
interesting vintage footage.

By the mid-1930's Fruit Growers Express was complaining about
competion from trucks as they were not regulated and could charge
whatever they wanted to. A pair of drivers could have a load to NYC in
two days and could charge a premium because their load was several
days fresher.

The show aires at 10 PM EST with reruns throughout the week.

I, too, wonder about "brand identification" here, Bruce, but do

not seem to recall large transformers with square ends until into the

1960's. It may be a question of cheaper to fabricate just as it has

been with locomotive housing. I wonder, however, if you might have

overlooked the Stewart Products cast metal transformers with the

rounded ends. These may no longer be available but were offered for

years and made great loads for deep well center flat cars. One would

make a great pattern for additional castings in resin.

Re: UP A-50-12 (converted to bunk car) about to be scrapped

Hi Folks

A UP A-50-12 (converted to bunk car) sitting in Laramie is about to be
scrapped. It was built by Ralston Steel Car Company in 1929, one of
the series 152001-152500. As far as I can tell it is still on its
original trucks.

Are there any particular photos or measurements anyone wants before the
car is gone forever? If so, contact me off list. The car is in
excellent shape.

Our leader Mr Brock was quite restrained in his response, but since you likely have a digital
camera, and digital images take virtually (snicker) no space, and could be put on a CD if they
challenge your hard drive capacity, I'd suggest you head out and take as many images as your
patience will stand. Underbody images would, as Mike said, be very useful, but all kinds of details
should be covered because once this is gone, it won't be possible to document it then. Many of us
take the standard 3/4 views, and call it done, but when you start to model something, there is
always< ONE more view that you wish had been taken.
Case in point: I am building the shake-n-take model Greg Martin organized, but I cannot find a view
that shows what kind of bracket was used to support the air hose. It's obscured by the coupler in
the one truly worthwhile photo I have to work with.

It might be useful to have photos of the car in general but, in particular, the underbody details might be useful.

Re: Polymer Corp., Ltd / Polysar tank cars

Steve,

My guess, to judge from both what the earlier-mentioned C&O employee and
the hints in the photograph suggest, is that the meaning of the entry is
that the car is insulated, and used for transporting latex. It doesn't
mention what sort of insulation it is? I could see it being some sort of
thermal insulation to prevent extremes of temperature?

The entry in the UTLX listing is very cryptic, consisting of

LATEX

at the top of the column with the car numbers. There are a number of car
groups with INSULATED, but this series is the only one with LATEX.

I agree with Kurt's suggestion of drinking straws.

While many of the straws on the market are oval shaped I finally found some
at a local coffee shop that were truly round (or so close to it that I
couldn't tell the difference.

They are 8" long x 200 thou dia with a wall thickness of 6 thou, so in HO
about 58' long x 1.5' dia.

The owner gave me two handfuls and that will do for all the pipe loads I'm
ever likely to need.

To "tie them down", I've bought some 1/64 black chart tape from a local art
supply house, to replicate the steel banding used.

Apart from the chart tape my cost was nil.

Re: Electrical Transformers

Kurt Laughlin <fleeta@...>
 

I suspect much of that may be "brand identification", i.e. Westinghouse vs. GE vs. Allis-Chalmers and so forth, but there does seem to be better ability to deal with excess heat these days leading to cleaner casings with less fins and heat exchanger pipes than in the past. Try searching on the OWI or Google/LIFE photo sites for "electrical", "transformer", "substation" and so forth and you ought to be able to find lots of dated photos. Yout typical hydroelectric dam, nuclear plant, or TVA article ought to have good pictures.
