I am in the process of creating a database for Frisco passenger cars. There are several coaches in the 1050's and a few in the 1060's and 1070's built by ACF in 1910-1912 that are divided into three separate sections, each with its own restroom (apparently for both sexes). Most had 40 seats in the main section, 20 in the center section and 18 in the other end. The seats and restrooms in all three sections were identical, so I can not see a class distinction for the separation. Two sections I understand, namely they were because of "Jim Crow" laws in the South. But I can't imagine what three sections were for. Many RR's had cars with smoking compartments, but I have not seen any with its own restroom nor any that were as large as the smallest compartment in these cars. Does anyone have any idea what these were?
