MODEL TRAIN DEFECT DETECTOR

Simulate a Model Train Defect Detector on your layout

NO COMPUTER NEEDED

Up for sale is an interesting product for your train layout: a Model Train Defect Detector (MTDD).The picture shows what the hardware might look like along a real train track.

We have been selling this product for several years now and have always used the sound card in a computer to create the sounds.This new product uses an MP3 player chipset to create the sounds.The sounds are stored on an SD memory card.

YOU DO NOT NEED A COMPUTER TO USE THIS PRODUCT!

 

The picture shows the entire Model Train Defect Detector that consists of: 

  • main unit measuring 8x3x1 inches;
  • power supply;
  • IR sensor pair.

All of the circuitry and SD sound card are mounted inside the black box.All the wiring connects inside the box.

The SD memory card is inside the unit.  All the sounds are stored on the SD memory card and get played (as needed) through the speaker mounted on top of the unit.  The speaker can be removed and mounted in a location on your layout if you desire. 

The MTDD includes a complete set of sound files and will work immediately.

HISTORY

Train Defect Detectors have been installed at strategic positions along railways for many years. The purpose of these systems is to automatically detect potentially dangerous failures in passing trains. The detectors transmit a voice synthesized alarm message over a railroad radio frequency to inform the train crew of a defect.

In operation, after the train completely passes the sensors, a "talker" will annunciate a message over the radio to inform the train crew of the number of axles, train speed and direction, and type of defect.  If a train passes without problem, the talker transmits a "no defects found" message over the radio.  After the equipment defect alarm is announced, the train crew will usually stop the train and perform an inspection to determine the cause of the problem. The crew will notify the dispatcher of the problem and how much of a delay can be expected.

The Model Train Defect Detector system presented here makes use of trackside infrared sensors to determine:

*The temperature is the room temperature measured with an onboard sensor.

*The defects are actually pre-programmed and occur randomly.  There are six possible defects.

LED/PHOTO-SENSOR

The LED/Photo-Sensor pair is mounted so the light beam shines across and slightly above the train track as shown in the diagram. 

The light beam is an Infrared beam and cannot be seen. 

There is an led on one side and a photo-sensor on the other side of the track.†††

Changes in room lighting will not have any effect on this system.

 

PLAY MESSAGE

 

The message says eBay Model Railroad.This is where the name of your model railroad would go.When you order the system just tell us the name of your railroad and we will replace the text in the message.†††

SPEEDOMETER

The speed of the train is calculated every time a train passes between the light beam sensors.The distance, between the light beams, is known and the computer measures the time it takes for the train to break both light beams.The science formula:Speed equals Distance divided by Time, is used to determine the speed. Since this product can be used on any scale train track, the scale speed is calculated and announced.

SOUND

All the local train personnel hear the results of the defect detector.This product uses an MP3 player chipset to create the sounds.You do not need a computer to use this product!  All the sounds are stored on an included SD memory card.†† Additional text can be added with the defect detectorís report such as your railroad's name, mile post and/or detector number.You can even vary the information in the report by having it randomly report errors.The included speaker is mounted on the MTDD box but can be removed and located in a building or under your train layout.

 

SCALE

Works with any scale train except N scale.

RANDOM DEFECTS

Rather than continually saying "No Defects", you can randomly announce defects from hotbox and dragging equipment detectors and/or clearance detectors.  There are six possible defects and the software picks one randomly.  You decide how often a defect will be found and reported.  For example you can have a defect found 10 percent of the time.  That means one defect will randomly be announced for every 10 trains that pass.  For the first 10 trains that pass, it might be train 2 that has the defect.  For the next 10 trains that pass, it might be train 8 that has the defect.

NO ADDITIONAL PARTS NEEDED

All the parts are included with the system including a 9-volt power supply.  A mounting kit for the sensor/led assembly is included with screws and spacers for different scale tracks.  The SD memory card contains a generic set of sound files on it.

Use Paypal or a credit card to purchase this product.  Please allow two weeks for delivery.

We also make other equipment for model trains.  Please check our website at www.cp4e.com.

RECORD YOUR OWN MESSAGE

You can also record your own message with your own voice using Windows Sound Recorder.A software program CD will be offered to help you do this.You will replace the sound files on the SD memory card with your own recordings.

LIONEL FASTRACK

If you have O scale and use Lionelís Fastrack, we offer a modified piece of straight track with the sensors built into it.In the picture we have mounted the sensors in a 10-inch piece of Lionel Fastrack.

In doing so the sensors require no tuning or adjusting and the TDD will work right out of the box.

We have also done the same thing to a piece of Lionel Fastrack for American Flyer and S gauge.

Ask us for details.

 

 

 

LOG TRAIN ACTIVITY

You can also connect the MTTD to your computer to log your train activity.This feature while not required for the operation of the MTTD, is an added feature.
