Passenger rail services are constrained by the ironic incompatibility between the privately owned railroads and track systems on which government funded passenger rail services operate, and the inability of passenger rail service managers to alter or improve any of the track, train systems or technology which they are confined to using. This rigorous separation of authority and ownership preempts all opportunities for creation of joint ventures or cooperative agreements between railroad companies, passenger rail authorities and any other potential private investors or operators of the passenger train systems.
Under these financial and administrative restrictions, no additional or new sources of revenue or investment are brought into passenger rail system development or operation. Virtually all government-administered and government-funded passenger rail services consequently remain static, inadaptable systems characterized by use of antiquated equipment, and providing unattractive, noncompetitive transportation service.
