TrainBoss™ Defect Detectors
Talking Defect Detector Model No. TB-22F/M
Modeling defect detectors of all eras, the Talking Defect Detector speaks and displays 6 types of defect alarms for passing trains with the probability you assign. The Talking Detector also reports axle count, train speed and length, and temperature — just like automated detectors on the prototype. For a bygone era, listen as rear trainmen report defects and speeding engineers. The Talking Detector can also be configured as a Displaying Detector. Speakers and Display Bezel not included.
New Features and Options in TB-22F/M:
- Male or Female Automated Voice
- Radio static bursts before and after automatic voice messages
- Greeting message when train is first detected
- Rounding up or down to ensure even axle counts
- Defect counts from end of train (as well as the original head of train)
- Additional words and phrases
The Voice Chip of your choice (male or female) is included. Please order by automated voice type:
Female Voice Model No. TB-22F $139.95
Male Voice Model No. TB-22M $139.95
Important: If your rail is larger than Code 125 (1/8"), please let us know. We will provide longer LED leads on your Axle Sensors.

Custom Word or Phrase Item No. TB-CWP
Boulder Creek Engineering is happy to add a word or phrase that's special for your railroad. We'll record and add it to the more than 100 words and phrases already included with the TrainBoss™ Talking Defect Detector. And we'll load it on as many Talking Defect Detectors as you order.
Custom words or phrases must be ordered separately for each automated voice type, male and female, if both are desired. For example, "Colorado and Southern Ry." in both male and female voice would be two orders of that phrase for a total of $20.
Be sure to include your email address with your order so we can contact you for pronunciation or other questions.

With a 40,000 - 200,000 lbs. readout, the WS-21M-200 is a 100-ton capacity scale typical for major yard installations and general Transition Era use.
Model No. WS-21M-200 $89.95
With a 0 - 160,000 lbs. readout, the WS-21M-160 is an 80-ton capacity scale well suited for lighter applications and narrow gauge in particular.
Model No. WS-21M-160 $89.95
Infrared Detectors
Instant Response Detector Model No. NS-350
The Instant Response Detector reacts to train arrivals and departures by immediately changing its outputs. This is the Detector for fast acting electronics that expect and can handle brief changes in detection, such as between railcars.
Model No. NS-350 $19.95
10 Pack of NS-350 $179.95
Delayed Response Detector Model No. NS-352
The red-jacketed Delayed Response Detector activates its outputs instantly when a train is detected. It will hold its outputs active for 2 seconds after the train departs. This prevents outputs from “bouncing” between active and inactive during gaps between railcars. The onboard LED still responds instantly, aiding installation and testing.
Model No. NS-352 $19.95
10 Pack of NS-352 $179.95
