Overmod tree68 Overmod Interesting point on that last page about the effect of fuel slosh on train handling. Note that they only mention it in conjunction with light engine moves and the use of the independent brake, not with full train movements. But note that the 'full train movements' in the BN case were solid loads like PRB coal. The only thing 'sloshing' is that context was the fuel tender, and that effect might be damped in long heavy consists with minimal draft-gear cushioning. The effect from slosh in a long string of virtually identical tank cars might be something else again. Was it Jeff Herbert who described 10' of delayed runout due to slosh?

Worked with a yard crew servicing a chemical plant with several tracks of tank cars - some full, some empty and some with partial loads - all without air. Slosh would move the engine and all cars in the cut upto 1/2 a engine length during switching moves. Even when having hold of 8 - 10 cars to Spot - bring the cut to a stop would have slosh that would move the cars 5-10 feet from spot - back and forth until the slosh attenuated - and then on to spot the next car. A tedious process for the crew and one that required skills for the cars to eventually stop 'on spot'.
With a loaded unitl oil train, I doubt that there would be all that much slosh as all the cars when loaded are near full and thus have limited slosh area within the car. Empties are that, empty so not enough product remains in the car to create slosh.
Never too old to have a happy childhood!

In that context, it makes full sense.

Interesting point on that last page about the effect of fuel slosh on train handling. Remember when Euclid brought this up in connection with oil-train accidents?

On the last page it states that there are pumps on the locomotives.
And a old thread here: http://cs.trains.com/trn/f/111/p/86247/1021918.aspx?page=1
But the link to the details is dead.
zugmannI'm guessing they held fuel filters?
Would suspect fuel heaters too, perhaps in an integrated module like the Ford FICM, and perhaps a transfer pump. Surely there is published discussion and pictures on this project somewhere we can link to it.
rdamonLooks like that series was equipped to connect to a fuel tender for use in the PRB as helpers.
I think you got it. The two brackets have holed in their side to allow a line to pass through them. I'm guessing they held fuel filters?
It's been fun. But it isn't much fun anymore. Signing off for now.

All EMD locomotives whose serial numbers start with the letter "A" were built at GM's London, ON, Canada plant until all production was switched to the Canadian plant early in the SD60 and GP60 production run, when the Canadian plant switched to using the serial numbers based on the Production Order numbers. The EMD plant at LaGrange, IL had been using this serial number system since 1971.
May have found it ...

This may have been related to that.

Yes ... looks unique to the BN 7100-7200 series delivered in 1980. They have a unique builders number starting with a 'A' according to : http://archive.trainpix.com/BN/EMDORIG/SD40-2/INDEX.HTM
May be interesting to see if this may be a tank used on the 50 or 60 series.
Okay, NS 3470 was supposedly BN 7215, and I can see the brackets, they look like they are connecting to something, but that could just be the angle.

Here is a picture of her sister BN 7255, which is in black and white, but you can pretty clearly see the brackets.

Now just to find out what is in them!

rdamonThe two shelf-like brackets on the tank?
That's them.
zugmann This is of another SD40, but has the same thing. NS 3470. Right below the EFCO button. http://www.rrpicturearchives.net/showPicture.aspx?id=4575142

The two shelf-like brackets on top of the tank?
zugmanna black thingie

Do you have a number for this engine, Unless I'm blind, which could be very plausible, I can't seem find an immage of a BN sd40-2 (and ex BN) with a bracket to hold something, maybe a picture could help.
edblysard Yellow thingie?
Yellow thingie?
It's a black thingie now. But so is everything else on the engine.
Nah, the yellwo thingies are on the trucks. I've actually used them to move markers around the yard. Probably the only person in my terminal ever to do so.

I was using an ex-BN SD40-2 last night. On the engineer's side of the fuel tank, there's a sort of bracket thing near the fuel fill. It's almost like a mounting plate for something that's now gone. Any ideas? Just idle curiosity.
