Circuitron #800-8100 Tortoise Remote Signal Activator. This device utilizes the Tortoise Switch Machine (sold separately) and a special drive wire cable assembly to remotely actuate any crossing gate, train order board or upper/lower quadrant semaphore signal having a vertical control wire extending below the layout.

Fully adjustable precise stops provided at both ends of travel for excellent repeatability. The total travel can be adjusted between 0.1” and 0.7” for use in all scales. This device can drive 2 cables from the one mechanism, if desired, for dual crossing gate installations. Includes installation instructions.

For 3-position semaphore signal control, see the Tomar #870 Semaphore Blade Signal Mechanism (sold separately).
