Description

Technical Field

[0001] The present invention relates to the technical field of rail transportation, and in particular to a side-mounted rail transportation system. Background Art

[0002] With the development of urban transportation and the automotive industry, the number of vehicles in cities, especially private cars, has increased dramatically. Traffic congestion, a prominent example, has become an unavoidable issue in urban transportation. This is especially true in large and medium-sized cities with large populations and complex road networks. Once congestion occurs, it causes inconvenience to people and is prone to traffic accidents. To address this issue, aerial rail trains can be used to share some of the traffic pressure in cities. This involves developing new rail transit systems in the air to alleviate the increasing traffic pressure.

[0003] Rail transit is an important part of urban transportation, and it carries an increasingly larger proportion of people's transportation. Rail transit not only makes people's travel more comfortable, but also effectively relieves urban congestion. The use of electrified power drive can not only reduce urban vehicle exhaust emissions, but also the use of electrified drive mode is a reflection of efficient resource utilization and an intensive method.

[0004] Urban rail transit systems are diverse and generally classified into underground subways, surface trams, and elevated light rail systems. However, the height of existing rail transit systems, typically consisting of the combined heights of support columns, track beams, and carriages, is high. This results in a large space requirement for these systems, making them difficult to construct on smaller roads and resulting in high construction costs. Summary of the Invention
