Poland will invest heavily in rail infrastructure in the coming years. In central Poland, ARCADIS is providing project management and supervision services for the modernization of a 37-mile railway track between Skierniewice and Lodz. The track is part of the 79-mile railway line between Warsaw and Lodz, two Polish urban areas having more than 3 million inhabitants. The modernization will lead to increased speed for passenger trains from 87 to 99 miles per hour, which will considerably lower the travel time for passengers. The comfort of passengers is also taken into account. A great deal of attention will be paid to safety and the elimination of noise and vibration
