Model Railroad Crossing Signal and Crossing Gate Control System
|
|
|
Where do most folks see trains in the real world? At a grade crossing. Visitors to your model train layout will connect your crossing signals to 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.

MRX2 includes a connection for non-flashing lamps, like these brake lights

Grade Crossing Signal Flashers
- Control circuits and flasher circuits for road crossing warning lights and crossing gates.
- Sophisticated microprocessor controller.
- Manual control capability.
- Easy to daisy-chain controllers for multiple parallel tracks.
- Compatible with most block occupancy detectors.
Now with 4-quadrant crossing gate control
What are four-quadrant crossing gates? Typical North American railroad crossing gates on two-way streets block traffic on half of the road. The gates cover the lanes of approaching traffic, but not the lanes leading away from the tracks. Foolish drivers sometimes cross the highway median, drive around the gate and get hit by a train.
To reduce collisions at grade crossings, railroads are installing four quadrant gate systems on high speed rail corridors, commuter lines, light rail systems and in areas with high concentrations of foolish drivers.
Four quadrant gates block all lanes of traffic on both sides of the tracks. Gate operation is sequenced. The 'entrance' gates close first, blocking approaching cars. Then the 'exit' gates close on the opposite side of the tracks. The delayed closing of the exit gates prevents vehicles from being trapped on the tracks.
Operation Lifesaver has a video of a prototype four quadrant crossing gate, [click here].
