1 How dedicated HS-lines will affect capacity on the conventional network Bo-Lennart, NELLDAL 12 th July 2012, Session: Operation 3 - Capacity

2 Content Rail system in Sweden Rail development in Sweden Plans for High Speed lines Evaluation of how HSL affect capacity on conventional lines Conclushions 2

3 Rail operation in Sweden - Mixed passenger and freight operation Freight trains in max 100 km/h Passenger trains in max 200 km/h Example: X 2000 tilting trains with average speed 150 km/h Many regional trains with average speed 80 km/h Freight trains with average speed 80 km/h (station stops included) 0 Förbigångsstationen använd för att köra fler persontåg och godståg Avstånd [km] Tid [min] 3

5 HSR in Sweden Town size Stockholm >1 milj inhabitants Göteborg 0,5-1 milj inhabitants Malmö thousand inh thousand inh. Uppsala Gävle thousand inh. Luleå Uleåborg Skellefteå Trondheim Bremen Göteborg Odense Trollhättan Ålborg Hamburg Skövde Varberg Östersund Lund Malmö Jönköping Köpenhamn Halmstad Helsingborg Plans for real High Speed Sundsvall network dedicated for passenger trains Bergen Falun Gävle Borlänge Oslo Uppsala in km/h Västerås ( mph) Stavanger Örebro Eskils- Stockholm tuna Norrköping Linköping Örnsköldsvik Umeå Åbo Tammerfors S:t Petersburg Helsingfors Tallinn Riga Performance Dedicated HSR 350 km/h Kiev Mixed possible 250 km/h Mixed maximum 200 km/h Mixed other lines 5

6 TVEM Time table Variant Evaluation Model 1. Representative traffic system for passenger trains will be constructed 2. Set infrastructure and train/vehicle characteristics 3. Time table analysis where position and time between the passenger trains will be varied 4. The space between the passenger trains will be filled up with as many freight trains as possible 5. Evaluation of the number of freight trains in each time table variant Constraint: Not more than 25% supplement in running time for freight trains caused by overtaking passenger trains Programmed in MATLAB by Olov Lindfeldt (PhD at KTH 2010) 6 6

10 Slots for freight trains per direction on day-time Capacity for freight trains with different investmentsstrategies for Stockholm-Gothenburg and Stockholm-Malmö Maximum 2008 With uppgraded main lines With high speed lines Järna - Hallsberg Hallsberg - Göteborg Mjölby - Hässleholm 10

11 Conclusions 2-3 times more freight trains in daytime on the old track if high speed trains move to a dedicated line At least quadruple capacity for high speed trains on the new line Reduced dependence and conflicts between trains Increased punctuality on both track pairs Extremely short journey times with high speed trains Building of dedicated HSL directly in Sweden is at the end cheaper than successive upgrading existing double track lines to four track and 250 km/h 11
