BLMA's Cantilever Signal Bridge model is based on a common Santa Fe/Southern Pacific style seen literally all over the USA.  Removed in mid-2006, the prototype was located at the very west end of Fullerton, California, on the BNSF mainline at a spot called "Basta". Cantilever Signal Bridges have been a part of railroading since the early 1900's.  Many early style cantilever bridges are still holding strong in spots all across the country, but slowly, they are being replaced by modern counterparts due to increased safety restrictions by the FRA (and perhaps OSHA) to keep signal maintainers safe while working on these structures. Features - All-Metal Kit - 100% Accurate - Extremely Fine Detail - Fun To Build - Includes Signal Heads (non-operating) - Includes Electrical box Prototype: The prototype for our model is based on a common Signal Bridge located throughout America.        The photo posted is the prototype item for the model.
