Does anyone know the AAR car classification for a dome car? I've got a hunch it's a type of coach, but.....
Class PL - domed lounge car

See the notation here:
AAR Letter Codes by Edmund, on Flickr
So the primary code would be the type of car since there were dome lounges, diners, sleepers, coaches, parlors, etc. then a footnote indicating the dome and, I suppose, what use the dome is, i.e. diner, coach or parlor.
I'll have to dig out an Official Register and take a look.
See note R and V:

No mention of a dome in the PL classification.
