The devices on top of the posts definitely appear to be electronic bells. Here is a link with more details on electronic bells:

General Signals bell from the link above
The wayside horns (for a "quiet zone" crossing) that I have seen generally have a horn prominently pointed at the oncoming road traffic, so it seems unlikely that the bells in Picture 2 also function as wayside horns.
