Trains in Latin America and the Caribbean mainly serve as a means of mass transit, bearing passengers along local and suburban routes of cities and transporting freight beyond. Non-urban passenger trains almost disappeared during the last few decades of the twentieth century. In the new emerging markets, however, demand is based on the train itself or the scenery en route rather than a wish to arrive at a given station as in the past. The new tourist trains, which are often well-restored historical engines, are expensive to operate and their special characteristics make it difficult to integrate them with mass transit railway services. However, some may be profitable when run privately and others may have a social justification, based on the boost they can provide to economic development in the often isolated and relatively depressed areas where they tend to operate.

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.
