Per the comment on the page they are 'platform clearance test cars'. So they would be used to test the clearance between the tracks and the platform to ensure that a freight train can safely pass the platforms.
And on top of that, were scrapped 4 or 5 years ago.
As for the reporting mark, they date from before GO picked up the GOT reporting mark, which seems to be about 1973 as far as I can tell. I'm not certainly GOOX was ever an actual, legal reporting mark.
