Lionel 6211-55 AEC Style canisters - what are they from?

There were about three production runs of the 6-6211 C&O Gondola between 1984-1986.

The ones that turn-up in separate sale boxes are typically the version with overstamping made for the Lionel Operating Train Society (LOTS). That version had two blue canisters and a coal bag.

But usually the 6211 was found packed loose in the 6-1402 Chessie System Set of 1984-1985. That version always had the yellow radioactive waste canisters.

There's also a scarce version of the boxed 6211 that predates the LOTS version, and this, too, has the yellow radioactive waste canisters.

They typically are seen with the Chessie Set 6-1402.

Thank you both for the information.

I remember that when I ordered them, I really wanted the round ones. So when I received the yellow AEC containers, I just put them away. I didn't even unwrap them.

Years later I paid too much for the red lens inserts that go inside the AEC canisters.  It did not occur to me that they would not have the terminal / power clips. To the best of my knowledge, the clips were not available then, so I didn't use them.

Fast forward to today.

The clips are readily available, as are the other components, so I was thinking about putting the AEC canisters together. I am starting to think doing so would be spending good money after bad.
