Updated list. Probably still inaccurate. I'm still wondering about #1260.
Former baggage cars believed to be in passenger service:
1953 ATSF Budd Baggage:
1159, 1161, 1164, 1241, 1248* (probably soon to go)
1955 ATSF ACF Baggage:
1260 (Likely the last ACF car on Amtrak's active roster) -- is this really in service? OTOL doesn't think so
1957 ATSF Budd Baggage:
1230
1950 SP Budd 44 Seat Conversion:
1709
1953 ATSF Budd 48 Seat Conversion:
1702-1703, 1710, 1714, 1716-1717, 1750, 1761,
1954 SP Budd 44 Seat Conversion:
1751
1752 (now "training car")
1753
1961 UP Budd 44 Seat Conversion:
1730-1731, 1733, 1735, 1738
(addition to original list) "Training cars" (origin unknown):
1762, 1232, 1231

So the very oldest car is #8554 from the NYC, built in 1946.
The oldest cars which seem to have no major modifications are probably #8521 and #8524 -- potential museum candidates?
The ones with the most conversions over their lives are the 1951 Pennsy Parlor Car and the 1956 CB&Q coaches.
