Just as the title and dose it mater if it has an antenna or not for year?
"One difference between pessimists and optimists is that while pessimists are more often right, optimists have far more fun."
PRR began experimenting with Train Phone in 1945 and got most of the bugs worked out by 1947. Equipment was gradually installed but not every locomotive or cabin car was so equipped.

By 1963 Train Phone was being replaced by two-way radio and the antennas and associated equipment was being removed. By 1967 very little evidence of Train Phone was left.
The PRR also used conventional radio usually in specific, larger yards. By the mid 1960s radio development (transistors) surpassed any advantages of Trainphone. There were just over thirty vacuum tubes in each trainphone set requiring frequent replacement and added maintenance cost.
PRR gradually removed the phone equipment and installed radio. "Radio Equipped" decals appeared on such equipment.
The last new locomotive delivered with trainphone was an Alco C-424, number 2415 delivered in 9/1963. A general order was issued on April 30, 1967 officially ending trainphone use.
