BLMA HO SCALE ASSEMBLED MODERN CANTILEVER SIGNAL BRIDGE
 Assembled & Lighted!
PROTOTYPE INFORMATION:
"Out with the old and in with the new!" This statement is perfect when describing signal bridges on class one railroads. At this point, older signal bridges are literally going out of style as they are torn down for modern, tube style bridges.
Unlike early bridges, today's giant, aluminum and steel structures are constructed of common parts, and thus, their appearance is nearly identical and any corner of the country. Combining ease of assembly, utilization of common parts and extremely easy accessibility for signal maintainers, all four of the current major railroads (BNSF, UP, NS, & CSX) as well as many smaller railroads have adopted this double-track style, modern cantilever bridge as the standard for their mainlines.
MODEL INFORMATION:
This model is the only modern signal bridge produced in HO Scale, period. Featuring four operating signal heads (a total of 12 separate, micro LED's!), super-fine detail, etched-metal components and 100% scale fidelity, this model is an asset to any modern HO Scale railroad!
FEATURES:
- 100% Assembled!
- Four Operating Signal Heads!
- Extremely Fine Detail
- Durable Plastic Construction
- Etched-Metal Handrails & Walkways!
- Extremely Accurate!
INSTALLATION INSTRUCTIONS:
This Modern Cantilever Signal Bridge comes completely assembled and ready-to-use right out of the packaging. The installation of this product will take two easy steps:
1. Mount on Layout:
Simply find the perfect spot for this double-track bridge on your layout and mount in place. The PDF link above provides an easy to use, "print and paste" drill template.
2. Connect Signal Circuitry:
This signal bridge has a total of 12 (#0603 SMT) micro-LED's preinstalled in the four separate signal heads. Each leg of the bridge internally houses four wires (one common and three for each separate, micro- LED: red, yellow and green). This bridge is wired in the common anode configuration (common positive).
With such a wide variety of signalling cicruits on the market, the signal circuitry has been left up to the modeler. All 16 wires will connect to the circuit of your choice to operate the micro-LED's (each of which takes no more than 2.0-2.2 Volts; 25 to 30 Mili-Amps).

* Atlas Signal System users note! After a great deal of research, it was determined that the new Atlas signal circuits are wired for a common cathode configuration. Seeing as almost all other circuits and signals on the market are wired for common anode, we chose to go with the industry norm (common anode). That being said, it looks as though the Atlas circuits will not work with this bridge (or any other common anode signal product). BLMA is working hard to find a solution to this.
