There are a number of photos of this truck in the Diver collection, including

Frist, as Richard H. points out, the dates are misleading. They refer to the lifespan of the photographer, DeForest Diver. Diver was an engineer on the O&W and also an avid photographer. He also seems to have a bit of inventor in him, holding a patent (http://nyow.org/diver.html)

As for the truck, looking at the other photos it seems that there is some sort of cable system to control sideframe pivot. I seem to recall seeing these photos in print somewhere....

An experimental truck of some sort, Richard, as I've never seen
evidence of a truck of this design in revenue service. And the
dating is wildly incorrect, as both the side frames and bolster are
steel castings, technology that wasn't developed until decades after
1870. Cast steel U-section side frames weren't introduced until the
1920s. As to the function of those cylindrical housings above the
journal boxes, I can only speculate - so I won't.

If you look closely at the left side of the truck, there appears to be a
bar running thru the U section, continuing under the center of the
sideframe, thence to the other cylinder. In the absence of obvious
springs, and what looks to be rubber absorbers in those cylinders, I think
they act as the springs for the truck.

Bill,
Unfortunately no. While the cars were "standardized" there were three
different door openings (6', 7', and 8'), each of which changed the
side panel spacing. There were also 4 ends that were used on ACF welded
box cars, 3 of which have been offered by Branchline Trains. Some ACF
standardized box cars used proprietary ACF Corrugated Ends and others
used what is called an ACF Riveted Roof, which had a double corrugation
on the roof panels much like the roof used by Armour as discussed in RP
CYC Vol. 21. Other ACF welded box cars used more common Murphy panel or
diagonal panel roofs. Now that Atlas has the Branchline tooling,
perhaps they can be convinced to produce some welded-side box cars.

Ed Hawkins

Hello Group,

In the September, 1990, issue of Mainline Modeler magazine there is an article with photos about the ACF Standardized Welded Boxcar. Has this boxcar ever been offered as a kit in HO Scale?

Thank You, in advance, for any information.

At any rate, when it comes to a shipment of oil, I'd rather unload through the
top instead of using the bottom connection.  Unloading through the bottom
connection means you'll end up with the water and sediment that has collected in
the bottom of the tank.

Another question I have is even with tank cars of gasoline did they need to prime the line from the tank car to the pump? I was told they used gear pumps that didn't need primimg.

There are customers who want to unload out the top of the car for
(perceived) safety reasons. If they have a rack to use during unloading,
they don't have to be under the car at all, except for steam
connections, if used.If a cap on the bottom is cross threaded and won't
come off, ("I already put and 8' cheater pipe on my 36" pipe wrench and
pulled on it with a fork lift:) the top unloading option is pretty
handy. Bottom outlet valves are notorious for being trouble. If the line
that is being unloaded into is low enough and all the connections are
good and tight the car will siphon out the top after the flow is
started.

If the vapor pressure on the car is high enough sometimes no addition
pressure is required.

Usually the eduction line is specified as being 1" off the bottom of the
car.

The dome can stay closed if the car is equipped with a vacuum relief
valve, which is basically a big check valve, but I am not sure when they

Subject: [STMFC] Re: Oil extraction




I can only admire the ingenuity in engineering methods of heating and
otherwise preparing the contents of a tank car for pressurized pumping
of the material up and out of the dome. But why not let if flow by
gravity and added pressure and/or heating if needed out of the bottom
valve?. Why fight gravity at all, ingenious or not? Thank you in advance
for informing me. Jim here.

The advantage of using the bottom outlet is to empty the tank. If you use the eduction pipe for off loading then there will be at least a couple of inches of product left in the tank as most eduction pipes are 2-21/2 inches off the bottom. The eduction pipe cannot go to the bottom of the tank as the diameter of the tank shell changes when the car is loaded and the pipe will make contact with the shell which in turn requires repair to the tank and or to the eduction pipe.

Jeff Coleman

Seems to me that if they used the bottom outlet, they would have to open the dome anyway to let air in as the tank emptied. And unless the tank was up on a trestle or was draining into an underground tank, they'd still have to pump it. So why mess with uncapping the bottom outlet, hooking up a hose, and opening the valve, when it could all be done through the dome?

I think there is a couple of photos of NKP single deck stock cars on the Fallen Flags site.

Can someone lead me to a good photo of a single deck NKP stock car?

Ed Mines

There is also the lettering diagram on the Elwood site. I can't see the
original date, but the first revision, "A", was in 1951 with the last
one "C" in 09-10-57.

http://www.rr-fallenflags.org/misc-frt/12-D-97.GIF

The drawing shows the Optic lettering, but because of the quality of the
scan much of the information cannot be read. With the wide handhold on
the left, the original looks like it was for the WWII plywood/wood
sheathed reefer.
