The OER carries the entire waycar series which includes the War Emergency Waycars WWII 14800-14890. These cars, while rebuilt from 40 FT boxcars of various builders, were all equipped with regular people doors on sides and none had doors intended for lcl or loading passengers. I didn't check on the WWI cars but they didn't have side doors either IIRC as they had platforms.
Were those 14800-14890 cars listed simplay as "Caboose" in the ORER, or some variation of "Caboose, (Box Car)?" ____ Mark Mathu Whitefish Bay, Wis.
