GO 95 explicitly prescribes contact wire height:
"74.4

B. Above Railways
(1) Tracks: The vertical clearance of 22.5 feet above rails for trolley contact, feeder and span wires of Table 1, Case 2, Column C, may be decreased to 19 feet where the railway involved does not transport nor proposes to transport freight cars."
As for minimum clearances around the transmission lines, that's another story, and the contact wire isn't a "transmission line".
