Model Railroad Crossing Signal and Crossing Gate Control System

Where do most folks see trains in the real world? At a grade crossing. Grade crossings on your model train layout will form a connection in the minds of your visitors between your model railroad and the real world. The more realistic your model grade crossings, the stronger the connection. Give your visitors a visual treat. A realistic operating grade crossing signal system will definitely boost the 'Cool' factor of your layout. It's easy to add sound effects with the Bell Ringer Module.

Free upgrade of MRX1 and MRXP modules Customers who purchased an MRX1 or MRXP before 28 Feb 2010 may exchange their modules at no cost for upgraded modules. Check the revision number of your circuit (see above). Modules may be exchanged if they do not have a revision number, or if the number starts with "9." Improvements include: • Enhanced overcurrent protection for MRX1 • More flexibility for users who use only one or two detectors. Contact Azatrax for details.

Grade Crossing Signal Flashers

• Control circuits and flasher circuits for road crossing warning lights and crossing gates.
• Sophisticated microprocessor controller.
• Manual control capability.
• Simple screw terminal connections.
• Easy to daisy-chain controllers for multiple parallel tracks.
• Compatible with MTH Rail King™ 'high rail' crossing signals.

MRX1 Flasher Controller Accepts input from 1 to 6 train sensors to simulate real world crossing signal operation. Sensors can be infrared train detectors, magnetic reed switches or block occupancy detectors. Flasher circuit works with all types of signal lights: Common anode LEDs Common cathode LEDs Back-to-back LEDs Incandescent bulbs Includes a connection for a non-flashing light at the tip of the crossing gates for the truly discriminating modeler. Signal lights circuit will supply up to 550 milliamps. Operates up to two slow-motion type switch machines to raise and lower crossing gate arms. Will operate non-flashing devices such as a banjo or wigwag crossing signal. Compact size: 2.5 x 2.5 x 0.65 in. Power required: 8 to 14 volts AC or DC.

MRXP Expander Circuit Use with MRX1 Controller (above) to protect an additional parallel track at the same grade crossing. Use an MRX1 for the first track, and one MRXP Expander for each additional track. Accepts input from 1 to 6 train sensors to simulate real world crossing signal operation. Sensors can be infrared train detectors, magnetic reed switches or block occupancy detectors. Compact size: 2.5 x 2.5 x 0.65 in. Power required: 8 to 14 volts AC or DC, 5 milliamps.
