Cable cars: An economically viable public transport system in #AmLat cities?

https://blogs.worldbank.org/latinamerica/cable-cars-economically-vi...


Did you know that in 2004 in Colombia, the Mayor's Office of Medellín inaugurated "Metrocable", the first cable car in Latin America (and the world) that functioned as a means of urban transportation?

Metrocable, in addition to connecting the marginal hillside neighborhoods of Comuna 13 with the city's metro system, demonstrated that cable car technology was viable as a mode of transport in mountainous or hillside urban areas, for distances of up to five kilometers. In the Latin American context, cable car helps vulnerable and predominantly low-income populations living in such sites, improving their urban conditions, and increasing access to job opportunities and other growth opportunities. Following the successful case of Medellín, in several cities around the world this solution was implemented.

The relatively low cost of construction, ranging from US$19 million per kilometer, in cities such as Medellín and Mexico City, to US$32 million in Guayaquil, and its rapid implementation (for example, the 4.1 kilometer Guayaquil cable car took 24 months to complete) have led more than 18 cities, mostly in emerging economies, to opt for implementing cable car systems within their urban transport infrastructure.

In addition to the advantages in terms of mobility, urban cable cars do not take up large surfaces, enabling public entities to provide and improve urban facilities. This generates socio-economic benefits in addition to those attributable to a transport project.

Why choosing this solution?

In the last years, public authorities and private actors have tried to understand business models used for this solution and variables that affect their success.

Faced with a growing interest to implement this system, the World Bank published in 2020 the study "Urban Aerial Cable Cars as Mass Transit Systems. Case studies, technical specifications, and business models". This is the first publication that brings together objective data on 21 urban cable cars projects, both in Latin America and other countries around the world, and includes a description of the main characteristics of the infrastructure, travel demand, and the business model adopted for their construction and operation.

The (World) Bank's analysis documented the cable car-gondolas technology systems, their relatively low implementation complexity, and found that the equipment supplier market (cabins and electromechanical equipment) is dominated by a limited number of European manufacturers.

Given this particularity of the supplier market, the Bank's analysis suggests that a decisive element for the success of these projects lies in the choice of the business model used for both construction and operation. Reviewing the inventory of modern urban ropeways, we found the following business models:

1. The Public works model, which is put out to tender the execution of works, with state operation and maintenance.

The La Paz and Medellín systems are in this category. La Paz has the most extensive urban cable network in the world, with 10 lines, more than 30 kilometers of extension, and an average of 160 thousand passengers per day. Medellín, on the other hand, has a network of 5 lines with about 12 kilometers of extension, and 40 thousand passengers per day.

2. In the PPP - public-private partnership – model, the concession for the service’s construction, operation, and maintenance are in charge of a private entity.

From Google Gen AI:


On May 23, 2021, a cable car on the Stresa–Alpino–Mottarone Cable Car crashed to the ground after a cable snapped.

The cable car was taking visitors to a mountaintop view of northern Italy's lakes. The cable car plummeted to the ground and tumbled down the slope, killing 14 people. The lone survivor, a young child, was hospitalized in serious condition with broken bones.

Investigators say the accident was caused by cable and brake failure. Charges including manslaughter and negligence are being considered. Three people have been arrested in connection with the accident.

The sole survivor of the crash was six-year-old Eitan Biran. His parents, brother, and two great-grandparents were among the 14 people killed.

Comment from Zia:Much safer than Pakistan railway

They are inspected often by the operator

Mostly are safe.. accidents are rare.

Cable snapping is the biggest problem but they is rarely a single cable. They mostly have in build redundancy with 2-3 cables running so if one snaps a rescue cop can be done with the other cables

What happened recently was mishap because of police stopping a rescue op and hence a delay happened

There was another snap cable few days ago rescue happened before the police arrival 😂 took an hour there
