I want to install some cantilever or bridge style signals over some double track spots on my layout. I need one signal per track. I can use either style but I would prefer the cantilever. However, when I look at pictures of a protypical Santa Fe cantilever signal, they are almost always a single signal head but I have seen pic's wth two heads. When I see multiple signal heads, they are almost always on a signal bridge with two legs.
What was the normal Santa Fe approach for mounting two overhead signals for double track? Was the cantilever with two signal heads an oddball setup that was only used in special situations where a full signal bridge would be a problem?
