A German semaphore main signal in combination with a semaphore approach signal. The main signal is the red/white one, the approach signal is the yellow/white one in front (and it of course relates to the next signal, which isn't in the picture). Both signals are of the three-aspect variety (proceed/proceed at restricted speed/stop) and show "stop"/"stop at next signal" here.
