A missing car took time to track down, often requiring workers to walk rail yards looking at cars until it was located. In 1959 David Jarrett Collins approached his employer GTE Sylvania to use a newly developed computer system in conjunction with scanners to track railroad cars. [1]
In the late 1960s, railroads in North America began searching for a system that would allow them to automatically identify rail cars and other rolling stock. Through the efforts of the Association of American Railroads (AAR), a number of companies developed automatic car identification (ACI) systems. The AAR selected four systems for extensive ...
Those on the Sunderland line are generally in the range 101 – 112, and the set operates all day on the Newcastle Airport to South Hylton route with this number. When on Network Rail metals (i.e. south of Pelaw to South Hylton) the initial digit '1' is replaced by '2I' to give a four-digit TOPS Train Reporting Number, e.g. train 104 becomes ...
