California Code, Public Utilities Code - PUC § 99603

(a) The department shall establish an advisory committee to assist the department in developing specifications for standard state-of-the-art California commuter and intercity rail cars and locomotives.  The committee shall consist of representatives from all affected local transportation agencies as well as the department's Division of Mass Transportation and one consumer representative.

(e) The committee shall consider two types of coach service, dining or cafe car service, or both, and economical sleeping car service for intercity applications.

(f) The committee shall consider inclusion of sanitary holding tanks and reasonable passenger amenities including, but not limited to, accommodations for a reasonable number of bicycles carried on board by passengers, for both intercity and commuter applications.

(g) Intercity equipment specifications shall not be adopted unless approved by the National Railroad Passenger Corporation.
