Though I have seen it many a times but do not know the exact mechanism of this. This looks to be for some counter balancing. Location is Mau Aimma on ALD-FD line. (Samar)

simple mechanics that will be lost in digital era....as has happened in aviation, normal hydraulic replaced by fly by wire.

This is just to keep the wires for semaphore signalling in proper tension. The counterweight for semaphore arm to put the signal in danger in case of wire break is a part of semaphore only.

Such counterweights are normally used for semaphore signals to put the signal to danger in case the wire breaks but this seems to be a temperature compensator and keeps the wires in proper tension.
