That "repeater" signal isn't a little broken down?
I mean, its indicating that the next main-signal is green [2 green lights] but the yellow plate is showing... that isn't correct or is it? Shoudn't the yellow plate be with the other position?

It seems to be broken. But it actually should show yellow lights, because the next main signal seems to show stop, as far as I can see. But actually it can be that the advanced signal has to be ignored when the main signal what is directly at the same position shows stop. As for the light signals of type H/V the advanced signal turns off, if it is attached to a stop-signing main signal as far as I know.
