Abstract

The country is experiencing a moment of improvement and evolution, which starts the expectation of new investments in the railways. It is a means of transport where there is accuracy in travel time, high load capacity and low costs, such as high gain access roads, when we understand that when done well, it increases cost levels and generates costs in the costs, which results in higher profits and consequently economic development. Existing modes, a history of the rail modal in Brazil, components that compose via track, technologies inserted in the sector, types and methods of existing maintenance and related costs will be addressed. They will be demonstrated in actual tests, or behavior of the most varied roads, under loading conditions and maintenance methods
