Signaling and Detection Implementation by a Customer

One of our customer recently completed a mock up and demonstration layout of the Precision Detector and Signaling system using fiber optic signals. His explanation is simple and clear and shows the complete setup including the latching feature.
Dan explains why he chose the system and what its capabilities are.
Please let us know what you think and please comment on the video.

Great job explaining this to the layman

[@ModelTrainTechnology]

Glad it was helpful!

[@jefferykeeper9034]

Actually there is a rail line in Illinois on the NS that uses the green as the default aspect.

[@lclarke1959]

Great video and very well executed in explaining how the technology works.

[@medwaymodelrailway7129]

Nice railway video .Hope there more to come.

[@ModelTrainTechnology]

Yes, soon

[@jolliemark6294]

Well done, I didn't understand the latching till I thought about it for a few minutes , but I did get it as your explanation did get through. Thanks this system could server a much easier signal system and more prototype applications, thanks for sharing 👍👍👍👍

[@ModelTrainTechnology]

Great!

Well explained. Nice system. Simple.

Glad you liked it

Good video my friend thank you for sharing Robert Guzman

[@yawarsaeed6499]

Awesome 👍.
Keep it up .

[@ModelTrainTechnology]

Thank you so much 😀

[@epacm50]

Awesome!!

[@ModelTrainTechnology]

Thanks!

Nicely Done. I wonder if there are plans to incorporate a way to keep a signal red while the block is occupied by a slow moving or stopped train using the latching of two detector circuits.

[@ModelTrainTechnology]

Yes, you can tie the output of multiple Precision Detectors together to create a "long" protected block.

[@yootoob7048]

@@ModelTrainTechnology Interesting. I would like to know more about how a protected block is managed as described at 2:00.

[@geraldjones2278]

How would your system work on a single-track mainline with trains moving in both directions?

[@ModelTrainTechnology]

A typical setup for bidirectional traffic on a single line is to put a sensor and a signal at each end of the block. Then, tie the output of the two sensors together and connect them to a single Signal Controller. In this way, if either one is tripped, the block is deemed to be occupied regardless of direction. You can put a Signal Light at each end of the block and connect them both to the single Signal controller. Also, If the train will pass the first sensor while entering the block before reaching the exit sensor - and thus the block may seem UN occupied, simply add a sensor ( or more than one) in the approximate middle so that the train is always in front of at least one sensor. With their output wires connected together they will act as one so that if any ONE sensor is tripped, the entire block is occupied.

Great info to bad nobody is making prototypical N scale signals like they have for HO...

[@ModelTrainTechnology]

Stay tuned... there are many variations in the works. Of course, there are dozen and dozen of types and styles so we will have to pick a few to begin with. The version in this video is a hybrid and was used to prove the concepts with both LED and Fiber. Given that the original video garnered more than 35,000 views since June 1, this is definitely a hot topic.

[@stevenV57]

Yeah, but writing lines of code is fun. 😑

[@ModelTrainTechnology]

Not for most people. :)
