If you're going to claim that it was debunked by the Director of the CIA, you're going to need to provide a link, please - ideally to a credible news organization or the CIA itself. I did a quick google and it came up with nothing, so it's very possible I'm not searching in the right way.
I'm not sure what articles you're referring to, but the first CBS article I found[1] says it could not be "independently verified".
>A video shared online of a train in Russia carrying equipment belonging to a Russian military unit that handles nuclear weapons should be taken as a message to the West, a military analyst says. The video, which a U.S. official told CBS News could not be independently confirmed, shows an armored personnel carrier with a cannon attached, as well as another vehicle belonging to the unit, being transported on the train, the analyst said.
The newsweek article[2] doesn't mention any sort of verification, and is repeating whatever the polish military analyst says.

>"We don't see any practical evidence today in the U.S. intelligence community that he's moving closer to actual use, that there's an imminent threat of using tactical nuclear weapons," CIA director William Burns told CBS News Monday.
>"What we have to do is take it very seriously, watch for signs of actual preparations."
The nuclear train story came out Sunday and this quote is from Bill Burns on Monday.
is different than
"that is not a train used by the nuclear organization, they are not moving weapons, etc "
He specifically does not address the claim. Which to me, is a red flag of lying by omission.
Personally, I never took the initial story super seriously, and view articles like this suspiciously.
