Several photos of the Helium Car

Browsing the Flicker site I discovered several high-res photos of that car, including construction photos.

Very en-light-ening! 

But seriously, thanks for posting. I found a couple of other cars of interest, too.

I see what you did there. 

I'm glad you found it useful.  Yes, lots of good high-res photos of interesting cars (especially tank cars for me). I'm about third of the way down through the 40+ pages of photos.

Always loved these cars...still saw the rare one on BN/BNSF in the 90's coming out of Amarillo, and then in the late 90's heading for the scrappers.

They have a couple at the Amarillo Railroad Museum.  I came across some photos while searching something else today.  I have my own, *somewhere*.
