Model trains and railroads enthusiasts realize that model railroad wiring is one of the most exciting and the most satisfying part of controlling the stop and runs of the set. All trains ought to halt at every station and need to slow down on every tight corner to prevent derailing. At every stop at every station, trains have a designated amount of time to load and unload passengers. To make this automatic run possible when operating model trains and railways, you need to do add some accessories and change wirings.
In order to achieve this goal, you have to identify where to separate certain parts of the track and to configure the circuit board wirings that will tell your model train what to do when it passes a certain portion of the track. A necessary accessory to be able to inform the circuit board when the train to stop is known as a photo sensor.
To slow down the train, an AS-1 circuit board is needed. A wire from the board connects to the isolated rail and another wire should be linked to the powered rail on the same isolated track. A train with a flywheel works best with this feature because it can slow down the train and start it up again. The train will regain its utmost velocity once it reaches a track that is not isolated.
For a train to stop, slow down, and start-up again a position sensor is required together with a DT-4, TD-1 and AS-1 circuit boards. Connect the DT-4 and TD-1 boards with a single wire. Then connect a wire coming from the DT-4 to the isolated track and connect a separate wire from the TD-1 on a rail from the same isolated track. A third line should join TD-1 to AS-1 and a wire from the AS-1 should connect to the non-isolated track.
The train will begin to slow down as it gets to the isolated track and will stop as it reaches the station where the photo sensor is placed. If you have set the time period on the circuit board on how long the model train would stop at a station, it will re-activate which will start the train again. As soon as it leaves the isolated track, it will pick up speed.
For a model train to go in reverse, you will be needing an AR-1 circuit board. Two independent cables from the AR-1 should connect to both rails on the track and another couple of wires connects to the photo sensor.
If you don’t know anything about wirings, you can just get yourself a DCC Digital Command Control set. DCC will let you control the train’s speed and path without getting any additional components and wirings.
