What is meant by the two-rail wiring principle?
The two-rail wiring principle is a fundamental concept in model railway wiring. It refers to the use of two separate tracks, each with its own electrical polarity, to power the trains on a layout. In this system, one rail is connected to the positive (+) terminal of the power supply, while the other rail is connected to the negative (-) terminal.
By using two rails, it allows for the creation of a complete electrical circuit. When a locomotive's wheels touch both rails, it completes the circuit and allows the electricity to flow, powering the train and enabling it to move along the tracks.
The two-rail wiring principle is commonly used in popular scales such as N, OO and OO9 gauges. It provides a simple and effective way to distribute power to multiple trains on a layout, as well as to control various accessories such as signals, turnouts and lights.
It is important to note that the two-rail wiring principle is different from the three-rail system used in some model railway scales, such as O gauge. In the three-rail system, one rail is used for the positive (+) terminal, while the other two rails are used for the negative (-) terminal.
Overall, the two-rail wiring principle is a key aspect of model railway wiring, allowing for reliable power distribution and control of trains and accessories on a layout.
