Abstract: A method for controlling communication between an off-board system and a railway wagon is provided. The method includes detecting a failure in communication between a first modem and the off-board system by, a first control unit. The method also includes determining a working mode of a second modem via a second control unit, by the first control unit. The working mode includes at least one of operational and non-operational. The method further includes receiving an identification number of the second modem from the second control unit when the working mode of the second modem is operational. The method includes establishing a communication between the first control unit and the second modem for transmitting the data associated with the first control unit to the off-board system based on the identification number of the second modem.

Abstract: An antenna array for a body panel of a locomotive is described having a base support including at least a pair of elongated parallel structures forming a channel on the body panel of the locomotive cab. A plurality of removable plates are affixed to the elongated parallel structures for mounting an antenna on each of the removable plates, thereby allowing wiring from each antenna to extend from its respective removable plate through the channel formed by the base support. A junction box situated near the base support forms an enclosure about an aperture formed in the body panel of the locomotive. The junction box includes a plurality of interconnects for connecting wiring of each antenna to wiring of a device in the locomotive. In one embodiment, the junction box is integral to the base support. The integral junction box, base support arrangement may further include a lip formed about its periphery in which a cover mounted thereon.
