Madrid - Seville Line

Before this high-speed line was put into service, the old rail route between Spain’s central plateau and Andalusia run through some very difficult terrain: Despeñaperros. With a single track and very tight curves (with a radius of between 300 and 600 m), it allowed top speeds of between 70 and 100 km/h. This route suffered from very high saturation levels.

Consequently, in the 70s, it was decided to study other alternatives for providing a higher-quality access to Andalusia. The first solution to be considered was to duplicate the existing track. This presented serious implementation problems due to the difficult topography and the fact that the works would interfere with the operation of rail traffic, since there was only a single track. These factors implied a high investment and adverse effects on normal operation of the railway.

In light of the above, the Railway Transport Plan (PTF, as per its acronym in Spanish) was drawn up to include the construction of the New Rail Access to Andalusia (NAFA, as per its acronym in Spanish), approved by the Spanish government on 11 October 1986. These works reduced the distance between Madrid and Seville by 100 km. The design of the route ran along the Madrid - Badajoz line as far as Brazatortas, where the new access to Andalusia began, going as far as the city of Córdoba.

The commissioning of the Paris - Lyon high-speed line (410 km) in 1981, and its growing success in the following years, suggested the need for a change of approach on the design of the infrastructure that was being built at that time. Therefore, on 9 December 1987, the Council of Ministers decided that the new infrastructure should be built using high-speed parameters and with the gauge that predominated in other European countries, i.e. 1,435 mm (the gauge of conventional Spanish lines is 1,668 mm).

Thus, high-speed trains began to be developed in Spain, but with an added problem: the political intention for the opening of the line to coincide with the inauguration of the World Expo of 1992, that was to be held in Seville.

Spanish engineers built the line in record time and, suddenly, a railway that had operated at 140-160 km/h was replaced by one running at 270-300 km/h with the first Spanish high-speed trains, a fleet of 24 Series 100 trains built by Alstom.

For travellers, the Spanish railway took on a new dimension while, in Europe, Spain put itself at the same level as France, Germany and Italy in terms of high technology. A significant historical event was taking place in Spain:the revival of the Spanish railway and the beginning of a new path to modernity and to increased competitiveness in Spain.

The design that was finally implemented solved a technical problem (low capacity of the old line), an economic problem (loss of passengers and freight) and, finally, a problem regarding the quality of service.

For the first time in Spanish history, the railway could compete with air travel, becoming the predominant mode of transport.

The Madrid - Seville high-speed line became a key indicator of the impact of high-speed rail on socioeconomic development and on territorial structure in the regions within its sphere of influence. This caused a ‘springboard’ effect, contributing to the development of the rest of Spain’s high-speed network, to the point where Spain has become a world leader in terms of its knowledge and experience of this mode of transport.
