CSX has about 12-15 cars in Office Car service. There are a number of different configurations. There are the traditional office cars that are configured for one or more Senior Executives to uses as office space while inspecting the property. The car will be staffed with a combination Porter/Cook jack of all trades to take care of the executive(s). There are also Diners and Sleepers for use in Customer inspection/sales trips where the number of people on the trip would surpass the ability of just a office car to support them. There are also HEP cars and other kinds of cars.
The cars are stored and maintained at the CSX facility at West Jacksonville that is in near proximity to the Dufford Dispatching Center. The business car locomotive fleet is maintained and serviced at the locomotive facility at Waycross, GA.
