When did the PRR discontinue use of its system of inductive train phones? And how fast was the equipment (in particular, the visible "handrail" antennae along the roof) removed from rolling stock equipped with it? Glancing at PRR locomotive photos on George Ellwood's "Fallen Flags" rail image site (invaluable resource!) I saw a couple of locomotive photos dated 1965 and 1966 that showed the antennae, but the 1967 and later photos that I checked didn't have them. (But I only checked a few.)
