Any analog model train and railroad hobbyists realize that model railroad wiring is one of the most important aspect and an exciting part of a model train collection. All trains ought to halt at each station and need to slow down on every tight corner to prevent derailing. Every stop at each station, there is a certain amount of time where trains can load and unload passengers. To make this automatic run possible when running an analog model train set, you have to know some basic and advanced wiring techniques.

To have an automated run on your analog railway you have to identify where to isolate certain sections 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 relay to the circuit board when the train is coming is called a position sensor.

To slow down the train, you’ll need a circuit board type AS-1. From the circuit board, one wire should be connected to the isolated rail and another wire should be connected to the powered rail on the same isolated track. A train with a flywheel works best with this feature because it can slow down and start up gradually. The train will regain its utmost speed once it is out of the non-isolated track.

For a train to stop, slow down, and start-up again a position sensor is needed along with a DT-4, TD-1 and AS-1 circuit boards. One wire should connect TD-1 and DT-4 circuit boards. 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 go 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. Depending on how long you set the duration for the train to stop on the circuit board, it will re-activate which will start the train again. As soon as it leaves the isolated track, it will pick up speed.

To reverse model trains, 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 are not much of a tinkerer, you can just get yourself a DCC Digital Command Control set. DCC will let you control the train’s momentum and route without messing with your wirings.
