[1] The system passes through 6 Administrative regions of the Federal District, those being Brasília, Guará, Águas Claras, Taguatinga, Ceilândia, and Samambaia.

Its main problem is the sheer distance between many stations (caused by overall low density, suburban profile for such system), making it only a small part of the transit system of the Federal District and mostly an intercity service, with exceptions in Brasília and Ceilândia.

The administrative region of Águas Claras is well-served by the system, making it one of the fastest-growing areas of the Federal District and the most dense.

Work was finally finished in the beginning of 2001,[4] and commercial service began on 24 September of that year.

[8] To deal with the increasing demand, 12 new four–car trainsets were purchased from Alstom,[8][9] with the first arriving in the Federal District in June 2010, leading to a fleet of 32 trains in total.

[1] All trains go through a period of engagement and dynamic tests, where all components of traction, braking, signaling and communication will be assessed.

Before the Alstom trains were put into operation, the Federal District Metro carried about 160,000 passengers per day.

A metre gauge light rail line was planned to depart from rail Terminal South and cut over Estrada Parque Polícia Militar road and travel south to 502 Nouth, a distance of 8.7 kilometers (5.4 mi).

It is one of three sections provided for in an online project to integrate a set of measures developed by the Government of the Federal District to revitalize the W3.
