Features: Around since the early 1900s, cantilever-style signal bridges are still in use in some places. This all-metal kit is based on a common Santa Fe/SP style used all over the country. The prototype is located in Fullerton, California along the BNSF mainline at a spot called Basta.

Features: Based on modern tubular signal bridges used by several major Class I lines and modern commuter railroads, this layout-ready signal bridge is ideal for your double-track lines.

This accurately scaled signal bridge features durable plastic parts and etched-metal walkways. Each supporting leg houses four wires, (one common and one for each LED). The model is ready for hookup to your choice of detection circuitry, sold separately.
