Embodiments of systems and methods include an access point onboard a vehicle configured to communicatively connect one or more computers on the vehicle to a path-based communication line. The communication line is adjacent to, or on, a defined path, and connects the vehicle to a connection point to a metropolitan or backbone network. Signals sent to and from the vehicle-based computers may be in one format or protocol. Signals sent over the communication line may be in another format or protocol. Signals sent over the metropolitan network may be in yet another format or protocol. One or more devices onboard the vehicle and/or at the metropolitan network connection point can convert between signal formats and/or protocols.
