| Summary / Description | Communication Technology is transforming the highly distance-intensive railroad industry. Speed, Information and Innovation are the rules of the `Wireless Revolution’ game. From crew-alertness to yard-management systems, this multi-billion-dollar rail market is moving onto the wireless fast lanes to boost productivity and gain a competitive edge. This article skims through the current mobile/wireless scenario prevailing in the railroad industry and the integrated rail applications that serve as a means to increase their bottom line. |

Excerpt Automatic Equipment Identification (AEI): AEI tags are installed in freight cars and mobile workers use readers to read these tags. When these are integrated with information from NDGPS receivers on locomotives, it enables railroaders to keep a tab on the precise location of every locomotive, car, shipment and train crew member- anywhere, anytime.Nationwide Differential GPS (NDGPS) is an extension of the Global Positioning System (GPS), NDGPS provides a few meters positioning accuracy to receivers capable of receiving the differential correction signal. |
A rail car tracking system (10) comprising: rail car location equipment (12) mounted to a rail car (22), the equipment (12) including a transmitter (26) for transmitting rail car location data to a remote receiver (21) and further including an electronically readable tag (33) attached to the rail car (22) for identifying the rail car (22) to a wayside tag reader (36); and locomotive communication equipment (42) mounted in a locomotive (38) and adapted for communication with the rail car location equipment (12) when the rail car (22) and locomotive (38) are coupled into a common train, the locomotive communication equipment (42) being operative to identify the coupled rail car (22) and including a transmitter (48) for transmitting data to the remote receiver (21), the data including rail car data so that the required data transmission from the rail car transmission equipment (26) is reduced.
| Relevance | See the excerpt. The article addresses combining RFID technology (an "electronically readable tag" as disclosed in the current invention) with GPS technology ("rail car location equipment" as disclosed in the current invention). |
