A system is disclosed for handling, storing, transporting and dispensing cryogenic fluids, liquid natural gas, compressed natural gas, and their equivalents. Internal valves are disclosed for dispensing such fuels from containers used in the system. The containers, in one aspect, are mounted in protective frame systems which are stackable and which provide access to the containers and the valves. A fuel injection system is disclosed for directly injecting LNG into an engine\s combustion chamber. Such systems include a railroad system in which a container of fuel is carried on a flat car behind a locomotive and the, e.g. liquid natural gas, is conveyed to the locomotive with appropriate valves, conduits, pumps, and controls. In one aspect tanks according to this invention have an internal relief valve. In another aspect valves according to this invention have an excess flow sensor and automatic shut-off device. In one aspect fuel fluid, liquid or vapor is injected into an intake (e.g. an air intake) on an engine.
