Mr. P is correct.

To me, it was always for a "Protective Device". You would look it up in the special instructions and it would tell you. Could be for many types: Spring switch, collision, fire, high water, slides and the list goes on. He is a sample off the Coast, TT 6

They would be listed under Rule 306. The following block signals equipped with a triangular plate displaying the letter "P" have included in their control limits some protective devise:

Eastward Signal Westward Signal

P-SA Spring switch, west end No. 1 siding Salinas
P-1878 Fire and collision detector Sargent Creek Bridge MP 188.15 P-1889
P-2278 Flood Dector East End Henry Siding MP 228.87 P-2289
