Currently, this line is used exclusively by freight services and is one of the main north-south goods routes.

By using this stretch, freight trains avoid passing the Lisbon area which has two significant restrictions: load limitations on 25 April Bridge and capacity saturation on the belt line and especially on the Northern line.

The main aim of this work is to expand the stations to allow the crossing of 750 trains, thus improving operating conditions and reinforcing the rail connection from the Port of Sines with national logistics platforms and with Europe.

Modernization of the Vendas Novas line includes the following work:

• Replacement of the track superstructure with the use of multi-purpose concrete sleepers and 60 E1 track;

• Extension and renovation of the Muge, diversion at km 19,5, Agolada, Salgueirinha, Lavre and Vidigal stations;

• Renovation of the remaining stations;

• 17 km of platform conservation (some at stations);

• Earthmoving, drainage and re-profiling of slopes;

• 69 water crossings (3 of which require suspension of the line);

• 3 metal bridges (which require suspension of the line);

• Closure of level crossings and construction of elevated road crossings with the respective re-establishments;

• Automation of level crossings;

• Work on the overhead contact line and cabling channel – construction of support infrastructure for signaling and telecommunications;

• Rehabilitation/remodeling and/or installation of drainage;

• Implementation of the Traction Return Current + Soil and Protection (RCT+TP) system;

• Work on buildings and technical rooms;

• Installation of GSMR towers and associated work.
