Tank Cars

Calvin · Upgraded Condition?

I think that some tank cars have larger diameter ends, as a result of double shielding to discourage failure of the integrity of the tank in a derailment.

This makes the car look like it is sagging in the middle.

Pipes FC · Enemy of the State

I'm sure they don't sag. I've seen them being scrapped in Columbus. Theres several layers. It looked like an outer layer, then fiber glass insulation, and then another tank.

Its neat when you stand next to one in the sun and you can hear the inside expanding.

Some could possibly be built to slope toward the middle to allow all of the liquid to completely drain when unloading.

Sounds reasonable ta me... That slight 'dip' in the center ta help the draining of the contents. Most tankers are dedicated ta haul one type of liquid. More often than not, petroleum product, which is not surprising considering how much oil we move.

On the northern lines, imports from Canada, tanks arrive in strings, with mixed trains outa Vancouver. A lot of that oil has been coming from Alberta's 'oil sands' fields. That's up here in PNW territory.

Down south, probably a more local source of the oil is close ta wes's area. Just like the coal sources... Think local. Coal, oil, natural gas sources are less costly when produced, then consumed close to the supply.

Economics. Shipping huge quantities of any bulk cargo, is cheaper (than trucks) by rail.

Three North American tank car builders... All of 'em follow standards set by AAR, and FRA enforces the standards.

And your eyes aren't playin' tricks on ya wes. Take a peek at American Railcar's schematic for a 15,000+ tank...

And here's two very typical tankers ta prove the point:

The cars are built with 'fatter' ends, and narrower center sections...and the vast majority unload from the botton center. All North American tank cars are 'lined' by a second inner tank, and food product tanks are usually buily with an inner 'fiberglass' third section, which is washed after every use.

This is old stuff, and I thank you guys that are trying to get me up to speed.

(But you can't polish a horse turd.)

My broken down old machinist eye has a good shot at these tankers while they cross a pair of overpasses in south Lexington. They are on Norfolk So. rails. I bet they are swaybacked at least 5 inches.

Knucklepin's answer makes a lot of sense if the drain point is close to the middle of the car.

Thanks again..................wes

Pipes, maybe you see it but I don't see it. Do you see it? Does Snippy see it? Just wondered.

That tank car sucked.

Krink can see it, *cy*.

Snippy thinks Krink must have given up on Talledaga. Almost four hour rain delay to go racin' into the night. Got to watch Danica's boyfriend fuck her on national TeeVee.
