The LB101 contains two independent occupancy detectors, each

of which can be used to detect that a train or piece of rolling stock

occupies a section of track. It operates on the so called “current

sensing principle”. The LB101 only detects occupancy when there

is a "current consumer" within the monitored track section

(detection section). The LB101 has been designed to detect a

decoder equipped locomotive or a single car with lighting or

resistor wheelsets.

MSRP is $24.95.
