25 - Infrared DCC block detection | Digikeijs DR4088OPTO

Using Infrared proximity detectors to detect passing trains and provide DCC feedback data over s88 and loconet. In order to automate my n-gauge model railway, I am using current sensing block detections to keep track of which train is in which block. However in order to be able to stop trains in a precise location, I am experimenting with embedding infrared LEDs and photodiodes in between the sleepers in order to detect when trains pass over the top of that track location. By using a Digikeijs DR4088 OPTO I can send DCC feedback information over the S88 network and then the loconet so that a computer running traincontroller, JRMI or iTrain can stop the locomotive at that location.
