SECTIONS
The classic Pullman accommodation, the "section" of a sleeping car was an open area with seats for daytime travel which were converted by a porter to an upper and lower berth. Later they were modified to have curtains for privacy. This was the most common way to travel on an overnight train during the heavyweight era .
COMPARTMENTS
The "compartment" was smaller than a "drawing room" and didnt have the sofa/bed.
SINGLE BEDROOMS
These were small rooms with a single bed. Later versions had a sofa which converted at night.
DRAWING ROOMS
The elite paid more for "drawing room" accommodations, which featured an enclosed room with a small couch opposite a seating section. At night the seats were converted to upper and lower births and the couch became a bed. These rooms were equipped with a private lavatory .
DOUBLE BEDROOMS
By adding a berth over the convertible sofa, the bedrooms evolved into double occupancy around 1930.
