Hi all,

I'm working on creating a set of CROR-compliant searchlight signals but am having a hard time finding source material for certain elements. In particular, I can't seem to find any real-world examples (or virtual-world examples, for that matter) of either the Direction Indicator (CROR #440) or the 'DV' letter plates. Does anyone happen to have a picture of either of these things, or some other reference material? I have the CROR rulebook itself but drawings only tell so much...

As an aside, if anyone with real-world railroading experiencing could explain CROR #438: Take or Leave Siding or Other Track and how it's used, I would be extremely grateful
