A dual rail system is a transportation framework that utilizes two parallel tracks for trains or other vehicles. This design allows for increased efficiency and safety, as one track can be used for incoming traffic while the other is designated for outgoing traffic. This separation helps to minimize delays and reduce the risk of collisions. In addition to trains, dual rail systems can also apply to other forms of transport, such as light rail or subway systems. These systems are often found in urban areas, where high passenger volumes necessitate a reliable and organized method of transit.
