Works involve the renewal of 39 kilometres of track and ballast, as well as 17 escapes and 12 turnouts, in the section that runs from Pantitlán to Observatorio, both on main and secondary tracks and shunting areas. The contract also includes the supply of materials such as sleepers, fastenings and ballast, among others.

The project also involves the rehabilitation of the electrical systems (low voltage, lighting, grounding, and continuity bridges), air conditioning in the technical rooms of the stations, pumping wells and their hydraulic systems, as well as minor structural repairs.
