Lionel 2026X

I learned today on an E-Bay posting that there was/is a Lionel 2026X. After searching the net and not finding anything other than there are additional 2026x’s for sale or auction I am no smarter that what I was when I started. Does anyone know why Lionel designated a few 2026’s with the X? Thanks, Steve

That locomotive is not a 2026.
As the listing states it is a 675 / 2025 with 2026x markings.

I am not very good at determining originality from online pictures, but it looks like it may be a repaint.

If so, then the refinisher just decided to use 2026X markings.

Then again, I could be wrong.

Take a look at the engine shown in this link.
Is it the same one?

Of the engine numbered “2026”, there was two different runs of them with variations. 1st run 2-3 years in the late 40s and 2nd run 2-3 years in the early 50s. I think there was a year or two between the runs.
