<{POST_SNAPBACK}>it would appear that the Viessmann banner-type signal you show, does work in a similar fashion the the UK prototype banner repeater........although the meaning of these signals is totally different!!

as john woodall stated, it appears to be a shunting signal......
Yes, that was my conclusion too. The closest UK equivalent is probably the red and white disc. However, according to the diagram in your link the German signal rotates so the black stripe slopes bottom left to top right when showing a proceed aspect. A British banner repeater slopes top left to bottom right as shown in the photo linked from my original post*. I guess this is consistent with the orientation of German semaphores, which in turn stems from running on the right. Napoleon has a lot to answer for!
*Some or all banners on the Western Region probably work(ed) the same as the German one, as that region used lower quadrant semaphores, but my layout is set elsewhere.
