Readers?
The article describes the code and the rolling stock side of the system, but what about the readers? Where were they placed, how did they look? How did they work? B/W cameras with color filters, color cameras, photocells with color filters? What kind of systems were attached to the readers? Was there a central entity for number assignment or was this handled by each RR company separately? What was the system-level goal of the whole system? Was it to know where rolling stock was located, was it for facilitating maintenance and lifecycle management? --Himbeerkuchen (talk) 10:51, 29 April 2020 (UTC)
I've tried to address some of your questions that I recall specific details for. There is only so much that anyone cares about 50 year discarded electronics so I hope I haven't given too much detail. Although the system had technical short comings I believe the demise was somewhat prompted by management and politics. Not everyone wants to know where a rail car is; the people paying rent on it for example. — Preceding unsigned comment added by K3SFD (talk • contribs) 14:18, 31 January 2021 (UTC)
Disagreement between picture and code diagram Suggestion
The picture at the top of the article of an actual KarTrak plate seems to disagree with the diagram further down which outlines the various bars allowed. For example, the STOP codes are inverted, and the first digit is an 8 which according to the text doesn't make sense. Clearly there is a lot of information missing here, someone should get that guy who knows a lot about barcodes [1] to check this page out. /-\urelius ♠ |)ecimus What'sup, dog? 14:14, 19 April 2015 (UTC)
