A fluid-jet emitting machine, particularly a firefighting machine, comprises a fluid-jet emitting device, a transport vehicle, lifting members and a control device. Each lifting member comprises an actuator constrained to the transport vehicle and at least one idler wheel adapted to engage a rail of a track. The actuators are configured to move the respective wheels between a non-operative position, in which the wheels are distanced from the respective rail, and an operative position, in which the wheels are arranged in contact with the respective rail. The control device is operatively associated with the actuators to activate the passage of the wheels from the non-operative position to the operative position so that during movement along a track and in said operative position, the wheels prove to be pressed against the respective rail, exerting a force such as to reduce only part of the pressure exerted by the movement means of the vehicle on the track.

A system for navigating within a track network includes, as system components, a system central, a track maintenance machine and a communication device. The system central is set up for administering network data representing a model of the track network. The track maintenance machine is suited for treatment of track sections of the track network. The track maintenance machine includes a navigation device for processing navigation data derived from the network data. The communication device is provided for data exchange between the system central and the navigation device. The system includes at least one movable or stationary carrier platform with sensors for collecting raw data representing characteristic information of the track network. A big data framework is set up in the system central to evaluate the raw data and synchronize them with the network data. Automated updating of the network data can be carried out with the system.

Personal transportation system includes plurality of personal transportation vehicles (PTVs) driven on a track network with series of track sections. PTV main section has lateral width adapted to contain single occupant. PTV driving mechanism propels PTV and includes track engaging element protruding downwards from main section and having narrow lateral width such that main section is prone to fall over when PTV is at rest. The space between lateral width of main section and track engaging element can be occupied by public infrastructure. Each track section includes a ground portion, minimally adapted to accommodate track engaging element lateral width, and an empty space above ground portion, free of non-transient obstacles and minimally adapted to accommodate main section lateral width. A guidance mechanism guides PTV along track network and prevents PTV deviating from track sections. A stabilization mechanism stabilizes PTV along track network and prevents PTV from falling over when turning/merging/diverging.
