The method shown below has been tested with sensor gaps as wide as 12 inches but a distance of 8 inches or less is more practical. There is also a method that can be used for longer range across track detection that could be used for yard throats. A detector circuit of this type is in use at the London Model Railroad Group's club layout and spans seven O Scale tracks using one infrared LED and a lensed phototransistor.
