(a) Coach-class - The basic class of accommodations offered by a rail carrier to passengers that includes a level of service available to all passengers regardless of the fare paid. Coach-class includes reserved coach accommodations as well as slumber coach accommodations when overnight train travel is involved.
(b) Slumber coach - Includes slumber coach accommodations on trains offering such accommodations, or the lowest level of sleeping accommodations available on a train that does not offer slumber coach accommodations.
(c) Other than coach-class - Any class of accommodations above coach, e.g., first-class or business-class.
(1) First-class - Includes bedrooms, roomettes, club service, parlor car accommodations or other premium accommodations.
(2) Business-class - A class of extra fare train service that is offered above coach class, but is lower than first-class, as described above.
If a train only has two classes of accommodations available, i.e., first and business class, then the business class is deemed to be classified as coach-class for purposes of official travel, as it is the lowest class offered.
