This subject came up in another post this morning, so I decided to share it this way as well. I have found this list of AAR codes helpful; there are links to the alphebetical listing at the bottom of the page. Big thanks to the Piedmont and Western Railroad Club for the time and effort it took to develop this listing!!

How do I get them to add SGRR before someone else gets it?
