This system allows the whole line to operate without any additional signalling personnel, and has functioned without major incident.
The bitting code is used in conjunction with a key's Depth and Spacing Number to completely determine all relevant information regarding the key's geometry. [1] Each number in the bitting code corresponds to a cut on the key blade. For example, a bitting code of 11111 with Depth and Spacing Number 46 specifies a Kwikset key with five shallow cuts.

The early color light signals were visible for only about half that distance (2,500 feet or 760 metres) while using about the same electrical current, then a major concern in "primary battery territory". By 1925, the development of "high-transmission colors" of railroad glassware by Gage and Corning Glass improved this limited distance to an ...
