Use with the Tortoise Switch Machine and an upper or lower quadrant semaphore-style signal.  Includes al the logic circuitry to drive the signal to all three positions. Works with BD-1 or BD-2 Block Occupancy Detectors. A minimum of two blocks must...

The CIRCUITRON DT-3 Single Direction Grade Crossing Detection Circuit utilizes our proven OptoElectronic Detection and will provide accurate grade crossing action for a single locomotive or a 100 car train. There are absolutely no modifications to...

CIRCUITRON designed the DT-2 to be the most advanced DC track power grade crossing detection circuit available at any cost. It is completely independent of train length and it will duplicate prototype grade crossing action for a single locomotive or a...

The CIRCUITRON DT-1 is a bi-directional detection circuit designed for DC track power that provides an output whenever one of its Opto-Sensors is covered by a piece of rolling stock. Absolutely no modifications to the rolling stock are necessary. 4...

The CIRCUITRON FL-2 is designed to be controlled by the output from one of our Grade Crossing Detection circuits. The FL-2 may also be easily wired for continuous flashing or for manual control with a panel switch, if desired. Only one FL-2 is needed per...

The CIRCUITRON EOT flasher includes the same LED as the CF-1. Refer to the description of the CF-1 regarding modifications to the LED which will result in a realistic HO scale device. After modifying, the LED is easily mounted on the coupler of any...
