Abstract
This invention is related to an economic and practical method of using barcode systems for the management of railroad tracks. The systems consist of barcodes and device(s) which can optically read and decode the barcodes. The barcodes are permanently installed on one or both rails of a railroad track at predetermined locations along the track. The barcodes include coded contents such as track location coordinates and other railroad property information along the track. By using these novel track barcode systems, sections of problematic tracks could be accurately located either manually or automatically for repeatable monitoring, repairing or replacement purposes.
Claims20
A track barcode system for railroad management purposes, comprising:
- (a) a plurality of barcodes for coding contents such as track location coordinates and other railroad property information;
- (b) a plurality of labels carrying said plurality of barcodes on a one-for-one basis, wherein said plurality of labels are attached firmly to a rail of a railroad track at predetermined locations along said railroad track to mark said track location coordinates and other railroad property information;
- and
- (c) one or more barcode scanners capable of reading and decoding said plurality of barcodes optically, for providing said contents of said plurality of barcodes.
A track barcode system for railroad management purposes, comprising:

- and
- (b) one or more barcode scanners capable of reading and decoding said plurality of barcodes optically, for providing said contents of said plurality of barcodes.
A track barcode system for railroad management purposes, comprising:
- (a) a plurality of barcode labels attached firmly to a first position and a second position of one or both rails of a railroad track at predetermined locations along said railroad track, for coding contents such as track location coordinates and other railroad property information;
- (b) a first barcode scanner capable of reading and decoding said plurality of barcodes attached to said first position optically, for providing said contents of said plurality of barcodes attached to said first position;
- and
- (c) a second barcode scanner capable of reading and decoding said plurality of barcodes attached to said second position optically, for providing said contents of said plurality of barcodes attached to said second position, wherein said second barcode scanner and said first barcode scanner could be one single barcode scanner;
- wherein said track barcode system uses said contents of said plurality of barcode labels attached to said first position and said second position to cross-reference each other for increasing system accuracy and (or) diagnosing damaged barcode labels.
