AAR Code Question

There are a number of AAR codes I cannot find: FP, THI, TRI, and XA. Can anyone help? Jeff



XA Automobile car. Similar in design to "XM", but with exceptionally large side or side and end doors.

don't know about the rest

FP - Flat Rack car. Ordinary flat car provided with side and end racks, with door openings in sides. Suitable for handling pulpwood.

XA - Automobile car. Similar in design to "XM", but with exceptionally large side or side and end doors.

THI - Insulated tank car equipped with heater device which permits intransit heating of lading. Apparatus operated by power other than through the axle.

I don't see "TRI" listed; I suspect it is an insulated version of a TR tank car.
