TODAY'S TRIVIA LESSON:
Whilst searching for the definition of a Parlor Car in another thread, I came across this gem:
From the 1943 Car Builders Cyclopedia:
AAR Recommeded Practice, Adopted 1910; Revised, 1942
(Manual-Page L-11)
A passenger train car is defined as a car suitably built to operate in passenger trains, its characteristics being: Passenger type of truck, passenger brake, air signal, steam train line, in accordance with definition and designating letters for general passenger equipment cars as follows:
Class "P"-Passenger
(types PA through PT omitted)...
"PV"-Private cars used as officers' or private individual's car and railroad pay car-usually composed of sleeping compartments, dining compartments, observation edn and with kitchen, servant's quarters and toilet and bathroom.
PV IS AN AAR TECHNICAL TERM!!!
... on the order of at least 60 years
