In a system where infrastructure management and operation are separated, it is customary for the operators to pay track access charges to the infrastructure company for every operating train. The charge usually includes costs of the energy required to drive the train. E.g. in Switzerland the charge is expressed as a cost per tonne.kilometre for every train category.

The Metro Los Teques rail link connects Los Teques and Caracas, and is being built as a double track mass rapid transit system. The line is approximately 9.5 km long, with an altitude differential of 180 m between both ends. For long stretches of track, the gradient is 2.7%, and reaches the value of 3.5% for 2.6 km. During peak periods, the line will be operated with 6-car trains travelling at 80 km/h at 4-minute headways.
