The 1990s: renewal and internationalisation Thanks to a great effort in technical renewal, staff training, investment in new machinery, research and development of new constructive systems, COMSA incorporated elements such as the Fast Track Renewal Train (TRT), unique in Spain, new tamping machines, renewal gantries, ballast cleaning machines, belt trains for removing debris, electric welding and even locomotives for its work trains. We are permanently seeking the latest technological advances to optimise performance and offer the greatest quality for each task. The internationalisation process was also started, founding the company Fergrupo in Portugal. 1992 Barcelona Olympic Games and the Expo in Seville 1994 The channel tunnel was opened, joining France and the United Kingdom In Spain, the nineties were marked by the AVE (high-speed train), the EXPO and the Olympic Games. Some examples of the work done during these years are the construction of the various sections of the AVE track between Madrid and Seville and of the EUROMED, new underground lines in Barcelona, Madrid, Bilbao and Valencia, the new Valencia Tramway or the permanent maintenance of the AVE and EUROMED lines, guaranteeing the required levels of quality. The constructions carried out in Barcelona, for the 1992 Olympic Games, went from improving the roadways and opening the city to the sea, to the creation of new areas that housed the athletes. New sporting facilities were also built, such as the Palau Sant Jordi, or the remodelling of the Sant Jordi swimming pool, in the Olympic Ring. 1995 Miguel Induráin won his fifth Tour de France 1997 Hong Kong was returned to China 1998 The euro, first steps for the new common European currency During these years, the company moved its headquarters to a new office to coincide with the centenary of its founding.
