A little help here.... *PIC*

I was in Galveston last week over Spring Break and stopped off at the Railroad Museum right by the cruise ship docks. A really nice place....very clean....and the model railroad exhibit was cool.
On the walking tour I "spyed with my little eye" a D&RGW SG Boxcar.
Its number is 63457.....it is in very bad shape as you can see right through the wooden sidewalls.
Any info as to how old this car is? And maybe how it ended up in Galveston?
I'm sorry this is the only pic...my girlfriends camera was stolen that night and it had all of my pics on it! This was taken with my camera.
