However there can be other uses such as automation and for keeping track of locomotives and cars. These blocks are detected blocks so when a train is in them, a signal is sent to a computer program. 8A capacity, suitable for all scales and track wiring configurations. The other way is block detector modules that detect the train but do not report back to your control system. A model railroad using DCC doesn’t need that, as trains can run independently on a single “block”, and the whole railroad could potentially be just one block. Chadwick Model Railway 78. (Block detection can be simplified by saying it is train detection. For example, knowing the occupancy status of each signaled block is essential to keep signals at red when the blocks ahead are occupied. Keep the track and signals operation off their own systems just for trouble shooting Enjoy HO scale locomotives of the top manufacturers and brands available. ) Also, when a turnout is thrown or changes position, a signal is also sent to the computer program.
