Re: B&O Wagontop
Gene <bierglaeser@...>
After reviewing all the pertinent discussion about the new Fox Valley B&O wagontop box car it appears that at least the first two paint schemes are legit and were in use before 1950. Sincere thanks to all who contributed to this conversation.
If I understand what has been posted the first scheme (below) is possible but would likely have been rare. B&O Oricinal Scheme (Flat Door) with no capitol dome herald on left side above reporting marks FVM 30301 FVM 30302 FVM 30303 This version would have been widespread once the B&O began using it. B&O 13 Great States (Flat Door) FVM 30304 FVM 30305 FVM 30306 Here's the link to Fox Valley's B&O wagontop box car on facebook: http://www.facebook.com/photo.php?fbid=10150097638299797&set=a.215654069796.1323\;07.92694309796&ref=nf Gene Green

Not at all. Tank cars could be and were cleaned for newHow would this be done, particularly after a load like tar or ashphalt? How would you scrub the sides of the tank? Or don't you think this is necessary? What about getting the last little bit of liquid (either the previous load or the cleaning solution) out? In one of the CBCs they show a revolving head which is inserted in the dome and squirts solvent throughout the car. Is there a guarantee that all of the previous load is gone? After a while the solvent gets expensive; disposal of a tank car of liquid (even water) is a problem too. A few years back someone wrote that they saw pictures of tank cars being cleaned out with steam. I think this would be done on cars used to transport crude oil and then common refined products like gasoline. Ed Mines

I work in a full service tank car repair shop and I can tell you that most customers use the bottom outlet far more than not for off loading all products.

I have a photo from the 1920's showing an Imperial Oil tank car being unloaded thorugh the bottom valve.

But using these valves can sometime be attended with problems. I was told (at a "TransCaer Safety Train" seminar on their demonstration tank car CCPX 911) of objects like pens falling into a tank after the bottom outlet cap (chained to the bottom outlet) was replaced on the outlet. Now, the bottom valve does not close fully, as that pen is stuck in it... On arrival at the consignee, their employee places a five-gallon bucket under the outlet to catch the half-gallon or so of product that will be trapped in the cap. He unscrews the cap, to find the valve partly open, allowing the contents of the car to drain into the bucket. Uh-oh! Now imagine trying to hook up the discharge hose to the outlet with product issuing from it. And what's in the car that may block and/or damage that hose? Flammable product spilt on the ground, a mess to clean up, and no way to stop the flow other than to replace the cap with product still flowing out of the car. Lost product = money. The mess will be expensive to clean up, too. Which to me expalins why many consignees preferred to unload tank cars by suction/eduction pipes rather than through that bottom outlet valve.

That's why right-side wheels turn clockwise and left-side counterclockwise, yes?Originally it was part of an explanation of the SP's "Tunnel Motors." I explained that due to the Coriolis force, there was a tendency for tunnels in the northern hemisphere to rotate along their long axes clockwise (naturally opposite in the southern hemisphere), tending to close them up, and that SP had applied small motors to the walls of its tunnels to exert an opposite torque and keep the tunnels open. Thus the name "Tunnel Motor." In the southern hemisphere, the voltage to the motor is simply reversed. Hopefully the Coriolis force, which is truly quite small, was overwhelmed in this case by the force of tongue against cheek.

1950s Flat Switching Film
Bob C <thecitrusbelt@...>
Here is a link to a 1950s Santa Fe employee training film titled "Payday".
This twenty minute short starts a little slow but then goes on to show a lot of flat switching action featuring nice slow pans of period rolling stock. Most of the cars are Santa Fe. It shows what happens when switch crews are careless even to the point of staging some minor yard accidents. Here is the link: http://www.youtube.com/watch?v=uNylLs4eoPY&feature=channel Enjoy.

Re: Oil extraction
gettheredesigns <rick@...>
Fascinating photos--thanks Doug. Some tanks had a "steam jacketed outlet" (ACF's name, illustration in 1925 CBC) that heated the valve and outlet pipe area. It looks to me like the small trailer had a pump on the far end that sucked the oil out of the dome, through the pump, and into the truck. The heavy (insulated?) hose to the outlet area could be the heating line, with the hose through the dome poked down into the outlet area to suck up the warmed oil. So the other apparatus on the trailer would be water and fuel tanks, and a small boiler. Informed speculation, tear it up Tony ;)

Re: Oil extraction
Group I have posted the two photos that started this thread, per Clark's
question. They can be found (when approved) in the photo album MSTL. The photos were taken by Vern Wigfield in June of 1954 in Marrietta MN, on the M&StL. Vern has given me permission to share his photos. The photos show URTX tank car 56816 being unloaded, via a pump trailer into a tank truck. There is a hose into the dome as well as from the bottom outlet. Doug Harding www.iowacentralrr.org

Re: Oil extraction
gettheredesigns <rick@...>
Hi Tony, it seems you misinterpreted by response to Jim Sabol's query. I'm aware that the valve is inside the tank, with the handwheel in the dome. The tank can only drain by gravity if the commodity is going into another tank lower than the bottom of the tank car. You are right, it's not a lot of work to hook up to the bottom--my point was that if the dome still needed to be opened, and the commodity still needed to be pumped, hooking up to the bottom would be additional steps that are unnecessary. From Clark's description of the photo, pumping would have been necessary, whether from the bottom or the top. They just opened the dome and dropped in the suction hose, and didn't mess with the bottom outlet. I stand by post.

Re: OK, What Kind of Truck is This?
Allen Cain <allencain@...>
Pure speculation from an old mechanical engineer but the cylinders look a
lot like what you see on the semi-trailers on the highways. This, combined with the absence of springs leads me to speculate that these are pneumatic shock absorbers. If you look closely, there appears to be a secondary frame behind the side frame which supports the bolster(?). So the load goes down through the bolster thru the interior frame passing through the shock absorbers and then into the visible side frames and to the wheels. Again, just speculation. Allen Cain

Re: unloading a tank car through the bottom valve

The bottom outlet valves used on steam era tank cars were 4 & 6 inch plug valves, the same design that's still in used today. On the tanks with expansion domes the valve handle (wheel) was located in the dome.

Yeah, Tim, but I still don't see anything that looks like a "steering arm", or a "steering arm center connection". What I do see are stops on the bolster that would lead me to believe it is some sort of swing motion truck, after all, the traditional swing motion trucks rely on swing links, under tension, to do their job. We can't see what the casting under the bolster actually does; with enough side play, the cable would act as swing links, although I don't see how they would lift the weight of the car, which is required to bring the truck back to equilibrium.
