BLMA has combined innovative manufacturing techniques with their nack for extremely accurate details to produce this all-metal signal bridge kit. Features: - Easy Assembly: Assembles in less than one hour with glue only.  This kit is fun to build and painting is a snap. - Durability: This is one solid model that can take the all too common beating while sitting over the mainline. The handrails are etched in stainless steel for exceptional durability. - Accuracy: BLMA is confident that if you took a tape measure to the real thing, the model would measure up perfectly! - Also Includes: Two, highly detailed and accurate Signal Heads (with room for the addition of LED's), four Concrete Footings and one 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.
