ACFX 4 truck tank cars - NALCO National Chemical Company

From the angles in various photos, the "inner" pair of trucks do not appear to be load bearing - if that's true, then what's the purpose of the extra trucks?  :D

I'm at a loss... perhaps my brain cell didn't load the sarcasm detection module on boot this morning. How could the inner trucks not be load bearing?

There is a span bolster that distributes weight to both trucks. The tank car body is supported by a connection to the span bolster between each of the trucks.

Edit: In the original picture you can see the open space above each of the trucks.

See my crude drawing here:

Yes, that photo link that Point353 posted led me to that conclusion - thanks! (I saw the light!)
