TPL P2- High-Speed Rail in Sweden – Supply and demand

The fundamental characteristic of high-speed trains on new main lines is they reach a high average speed, often exceeding 200 km/h with top speeds between 250 and 360 km/h, and thus achieving competitively short journey times. When express and fast trains on the conventional lines are replaced by high-speed trains on the new main line, capacity is relieved for expanding freight train and regional train services. Punctuality is also improved by separating slower and faster trains.

KTH Railway Group has participated in several studies and research projects concerning high-speed trains. During 2009 KTH Railway Group participated in the commission on high-speed trains appointed by the Government. In 2010-2012 we participated in a similar assessment for the Norwegian rail administration (Jernbaneverket). In 2012- 2015 minor commissions for future high-speed projects including an upgraded connection Oslo–Stockholm have been performed, as well as continuous support in the planning of the Swedish high-speed system. During later years, we have had a continuous dialogue with the New Generation Railway (NGJ) high-speed rail project of Trafikverket. The aspects discussed includes system requirements and technical standards, and not at least the performance of the national demand forecast model.
