Georgia Pacific owns a fleet of 500 tank cars with reporting marks GPBX, GPSX, GPMX, GPPX, GAPX. I have a Georgia Pacific chemical plant on my layout and a bunch of old tank cars. I would like to repaint a few of them to become GP cars. So far I have been unable to locate any pictures of any GP tankers. Does anyone have any they could post or could anyone point me in the proper direction to find some?
