" ...The BD-16 is a fully integrated train-detection system. It uses diode current sensing to detect the presence or absence of a train, or to differentiate between East and West travel..."
" ...We saw many top-notch systems being demonstrated at the NMRA National Convention in Atlanta last year, and after a short discussion decided on the BD-16 because it was simple, and it fit our budget..."
" ...Mr. Ataras is committed to this product, and wants his customers to be satisfied. I would happily install one on my layout..."

"...W.S. Engineering has entered the hobby with the BD16 Block Occupancy Detector, a detection device that can handle 16 track segments (blocks) at a time and provide a variety of outputs for control panel lights, signals or accessory activation..."
"...I have wired the test sample into my ten-year old layout, and I am using the outputs to drive control panel lights in some cases and as input to TTL signaling in others. The detector is working perfectly, and I am very pleased with the results..."
"...In short, the BD16 Block Occupancy Detector is sophisticated, well thought out, well made and supplied with an excellent instruction book..."

"...The TC4 is the latest electronic device from W.S. Ataras Engineering and controls three-light signals for four blocks and is designed to work with the company's BD-16 block occupancy detector, although it can be used with any detector that produces a TTL compatible logic output..."
"...The TC4 is so versatile that it provides a 27-page instruction book to cover all the possibilities..."
"...Simply stated, the TC4 works flawlessly. At a list price of $70.00, the controller is an efficient and cost effective way of extending three-color signaling to appropriate parts of your layout.

"...the BD8 provides a variety of outputs for control panel lights, signals or accessory activation..."
"...This detector has been designed with all types of layout in mind..."
"...In short, the BD8 Block Occupancy Detector is an excellent addition to the Ataras line of sophisticated electronic products.
