Yo, Clem, I have done just this and: Section 5.1 contains a diagram showing "Overhead Contact system Zone and Pantograph Zone" which extends up to 26 feet to allow for broken pantographs and overhead failures (broken wires). Undoubtedly this has to do with the "extreme overpass heights" others were wondering about and which is not what I was talking about. There is a notation on the diagram of "highest part of the overhead contact system" which is quite a bit lower, no dimensions given. GO 176 makes frequent references to specifications given in GO 95, where Table 1 case C specifies contact wire height as being 22.5' for voltages of 0-5,000v. This is the comment I was answering: contact wire height, not bridge or overpass height, and I could find no language in either GO which modifies this for voltages above 5,500.
These regulatory documents use convoluted structures and opaque and dense phraseology, so please you stop and do what I do: quote chapter and verse if you feel someone has erred.
