Advantages of Monorails
Urban Mobility Solutions:
Monorails provide an efficient means of urban transportation, especially in densely populated areas where space is limited. They can ease congestion and offer an alternative to traditional modes of transportation like buses and trains. More recently, monorails have been used in projects with longer systems between urban centers. Monorails, being elevated, are not exposed to the disturbances of other systems that are at-grade, running on congested streets, or with the presence of animals or pedestrians. They are economical to build compared to heavier systems.

Environmental Benefits:
Monorails are often seen as environmentally friendly due to their use of electricity and lack of direct emissions. They can contribute to reducing air pollution and dependence on fossil fuels in urban areas. They are the elevated system with the minimum use of concrete compared to other mass transit elevated systems.
Scenic Views:
Elevated monorail mainline structures can offer passengers panoramic views of the cityscape, enhancing the overall travel experience and potentially attracting tourists. Examples of monorail scenic views are the Tama and Shonan monorails in Japan, where people can see the Fuji Mountain by the train.
Integration with Existing Infrastructure:
Monorail systems can be integrated with existing transportation networks, including metro lines and bus routes, providing seamless connections for commuters. Having a new mode in a metro ‘system’ might be considered a downfall for metro operating systems, however it is very rare to have metro systems with the same rolling stock supplier across lines, which exposes the operator to the same lack of uniformity. Monorails can be used as feeder lines to connect existing infrastructure or existing or future buildings or developments, in the same way the subways were used in London to extend the city into future developments away from the city core, in more affordable metropolitan areas.
Flexibility of Elevated Track Beams:
Monorails are a lightweight transportation system compared to other elevated transportation systems. Monorails are composed of guideway beams typically supported on one column, which is then supported on a monopile in most places. This system results in many advantages:
- Monorails can be erected faster with less cost.
- Different types/shapes of columns can be used; rectangular, circular, etc.
- Reduced cost of construction by using a few types of molds for construction of supporting elements within most of the alignment.
- Monorail systems require a small area on the ground for columns only.
- High quality control is achievable due to using precast elements such as guideway beams.
- Monorails have strong grade capabilities and a small turning radius, providing adaptability to existing terrain.
- Monorails utilize 40 to 50% less concrete than any other elevated transportation system, thereby diminishing their environmental impact.

Capacity Flexibility:
Monorails, like many transportation systems, can be designed and configured to accommodate varying levels of capacity based on factors such as train frequency, car design, and station layout. The capacity can range from 2,000 passengers per hour per direction (pphpd) to systems like Line 15 in São Paulo and the planned Cairo monorails, both boasting capacities of more than 40,000 pphpd. This capacity demonstrates the potential of monorail systems to efficiently move varying volumes of passengers, contributing significantly to urban transportation networks. As urban populations continue to grow, and cities face increasing pressure to develop sustainable transportation solutions, the capacity of monorail systems can play a crucial role in meeting the mobility needs of residents while reducing congestion and environmental impact.
Development Opportunities:
The construction of monorail systems can stimulate economic development along their routes, leading to increased property values and commercial activity in adjacent areas.
