¿Buses o tranvías para las avenidas de ciudades latinoamericanas?

Una vez, el transporte público en casi todas las principales ciudades de América Latina dependía críticamente de servicios de tranvía, los que se extinguieron hace unos cincuenta años, por una serie de razones. Ahora, especialmente en las ciudades del mundo más desarrollado, regresa el tranvía, en una versión moderna, conocida generalmente como light rail transit. Sin embargo, en América Latina se ha desarrollado un concepto autóctono de servicio urbano de transporte masivo de pasajeros, en la forma de buses de alta capacidad que transitan por vías exclusivas, de una manera integrada con el resto del sistema de transporte público. En general, esta solución latinoamericana puede ser más indicada para las necesidades de la región, por razones de flexibilidad, costos y capacidad.

The Contribution of the Economic Commission for Latin America and the Caribbean (ECLAC) to the Physical Integration of Transport Systems in South America: A Historical Overview

For over a quarter of a century, the Economic Commission for Latin America and the Caribbean (ECLAC) has been in the vanguard of the search for greater physical integration among South American countries, especially in the area of transport, including road, rail, river and multimodal transport.Its activities in this field have ranged from drafting agreements to the design and introduction of concrete measures and have been carried out, either individually, at the request of the Governments of member States, or in collaboration with other organizations, such as the Institute for the Integration of Latin America and the Caribbean (INTAL), which is part of the Inter-American Development Bank (IDB).

Buses or trams for Latin America's cities?

There was a time when tram services were critical to public transport in many of the largest cities of Latin America; however, trams disappeared about fifty years ago, for a number of reasons. They are back now, especially in the cities of the more developed world, in a modern version usually known as light rail transit. Latin America has developed its own concept of urban mass transit, namely, high-capacity buses operating in special lanes as an integral component of the overall mass transit system. As a general rule, this Latin American solution seems to be the best suited to the needs of the region, given its flexibility, cost and capacity. Each situation must be assessed separately, however, and in some cases, a modernized version of the tramway may be the best solution.

The opportunities and risks associated with privatizing railways in Latin America

Most railways in Latin America were built by private firms, often foreign owned. Over time, owing to a combination of nationalizations and competition from road transport, virtually all railways passed into government hands; the railroad industry became more and more of a white elephant for the Government because of the ever-increasing subsidies it swallowed up, its dwindling role in national economies, and a conviction that Governments should not be involved in productive activities. Consequently, the late 1980s saw the start of a trend towards denationalization of railways, with the latter being turned over to private, often foreign, interests. In this way, the railway industry in Latin America has come full circle in the space of 150 years. So far, there has not been any assessment of the recent privatization of railways in Latin America. However, the conclusion would probably be that: (i) privatization has on the whole been successful, and (ii) the results achieved would have been more positive still, had some things been done slightly differently. One problem is that the bidding process has failed to take into account the positive externalities associated with railways, such as the contribution they make to reducing road maintenance costs and environmental damage caused by road transport. Another unresolved issue is whether to put the entire railway system up for tender, or to invite separate bids for infrastructure and services. Economies of scale operate in the railway industry, favouring the existence of a number of rail companies. In the past, the railway companies of neighbouring countries such as Argentina and Paraguay, and Bolivia and Chile, enjoyed ties at director level, but these came to an end with the nationalization of railways. Now that the era of State involvement is itself drawing to a close, we can expect to see the formation of integrated railway systems, one of which might extend from Quijarro, on the border between Bolivia and Brazil, to Puerto Montt in the south of Chile.
