Just to clarify: boxcars are all done, but some of the other cars aren't all done.The current latest are the boxcars: http://hawkdawg.com/forums/viewtopic.php?p=44828#p44828 . It's still a WIP because they are not all done yet.
Cars that are all done include: Autoracks, Boxcars, Cabooseses, Express up to 1925 (still using defaults from 1925 onwards), Open and Covered Hoppers (although I want to revamp them a bit anyway), and Tankers (also being revamped, just because I can).
Flatcars, Reefers and Stock Cars are not done yet. Also the latest spreadsheet is a tad different to the ones already posted, just because we have thought of a few more things since then.
