I picked up my pre-ordered Lionel PRR X31a boxcar last week, plus the Lionel PRR X31a double door boxcar I bought off this forum also came. Both look great and pretty much match the pictures of the actual cars on the web.
The only problem I have is with the boxcar. The X31a was built from 1934 to 1936. The double door boxcar has a build date of 6-36, while the boxcar has a build date of 6-56.
Like I said, they almost got it right.
