Abstract
A rail system is disclosed. The rail system may have a track including a wireless communication zone and a wired communication zone. The rail system may also have an electrical contact that extends along the wired communication zone. The electrical contact may be configured to transmit electrical energy and a data communication. The rail system may further have a power source electrically connected to the electrical contact. The rail system may additionally have a controller selectively electrically connectable to the electrical contact and a wireless network. The power source may be configured to transmit electrical energy through the electrical contact. The controller may be configured to switch between data communication transmission via the wireless network and via the electrical contact, based at least in part on a location of a rail vehicle within the rail system.
