In the future, it is planned to extend this rail line to the city of Barbalha, south of Juazeiro do Norte.

The inauguration was scheduled for February 2007, but in January 2007 work on the line was halted due to the change in state government, and was only resumed in June 2007.

The Cariri Metro's single passenger rail line, called the Central Line, serves a total of nine stations, and runs over a total length of 13.6 kilometers (8.5 mi), consisting entirely of an at-grade rail route.

The fleet generally consists of a LRV trainset composition which is formed by two air-conditioned cars,[4] and which are capable of carrying up to 330 passengers per train.

The trainsets are built by Bom Sinal Indústria e Comércio Ltda., a company established in the municipality of Barbalha.
