A bi-level (double-deck) passenger coach without its own propulsion system classifies under 8605 regardless of its configuration, since the defining criterion is the absence of integral traction equipment and the vehicle's passenger-carrying purpose. The number of decks, seating configuration, or amenity level does not affect the heading classification.

A private rail car designed for passenger accommodation and hauled by a locomotive falls under 8605 as a special-purpose railway coach, even if it is not used in scheduled passenger service. The heading text explicitly includes 'other special purpose' coaches, which encompasses private, charter, and excursion cars that are not self-propelled.
