In July of 1952 the IC ordered six 11-bedroom sleeping cars from Pullman- Standard for assignment to the "City of Miami" and "Panama Limited." The cars were built to Plan 4168A and delivered as Lot 6912 in July of the following year. The cars were named as follows, with the numbers in parentheses being applied in 1969: Baton Rouge (3500); Belleville (3501); Benton (3502); Bloomington (3503); Brookhaven (3505); Bradley (3504). The cars rode on 41-BNO-11 trucks and used Safety Industries electro-mechanical air conditioners. All of the cars were sold in 1970-71 to private parties.
