ATSF 999794

The artists helpfully made sure the caboose’s ID number was still visible.

update: According to the twitter hivemind (thanks @kzodasnowman and @evanheisman!) the artists leave the numbers exposed (or in this case repaint them in big letters on top of the art) so the railroad people won’t come and paint over the art.

Also, there’s a trainspotting web site with a bunch of pictures of ATSF 999794 through history!
