Togdrift i Nordjylland - En ekstra togforbindelse over Limfjorden: En ekstra togforbindelse over Limfjorden

Abstract

I nærværende kandidatspeciale er inddelt i to dele. Første del omhandler hvilke tiltag og visioner, der har indflydelse for jernbanen i Nordjylland, fra 2000 og frem. Af tiltag og visioner er bl.a. nyt signalsystem, opgraderet hastighed, jernbaneforbindelse til Aalborg Lufthavn, elektrificering og ny køreplan med regional fokus. Det er vurderet at elektrificering kan vente til 2030 da Nordjyske Jernbaner har indkøbt nye dieseltog. Planen for elektrificering i Nordjylland er mangelfuld og bør inkludere Skagensbanen og Hirtshalsbanen hvis Nordjyske Jernbaner skal forsætte ned til Skørping. Den anden del omhandler de problemstillinger, der er ved en jernbaneforbindelse til Aalborg Lufthavn. Det er undersøgt om en udvidelse af Jernbanebroen over Limfjorden er en god idé. Det er vurderet at det ikke vil være nødvendigt for togtrafikken, da den nuværende kapacitet er tilstrækkelig. Det vil kunne lade sig gøre med k13 køreplanen at tilpasse tog til Aalborg Lufthavn, med to tog til Lufthavnen og to tog til Vendsyssel. Behovet for passagere i fremtiden er undersøgt. Tre tog vil være optimalt. Tre tog i Vendsyssel vil dog ikke kunne lade sig gøre med den nuværende infrastruktur, da krydsninger nord for Lindholm ikke passer til en 20 min drift. Løsninger kan være en opgradering til 200 km/t. Eller ny krydsning mellem Brønderslev og Vrå og forlængelse af dobbeltspor ved Sulsted.

This thesis is divided into two parts. The first part deals with the policy plans and visions that have an affect the railroad in North Jutland, from 2000 onwards. The initiatives and visions include new signaling system, increased speed, railconnection to Aalborg Airport, electrification, and new timetable focusing in the regional raillines. The first part of the project will also look at constraints of North Jutland, including: • Rail blocksections • Signaling system • The railtrack • Rolling stock • Electrification • The rail bridge over Limfjorden • Operating speed. It is estimated that electrification can wait until 2030, as Nordjyske Railways purchased new dieseltrains in 2005 and 2017. Furtermore, it is estimated that the trains have a lifespan between 20 – 30 years. The plan for the electrification of North Jutland is not sufficient and should include Skagensbanen and Hirtshals, if Nordjyske Jernbaner is wanted to continue to operate the railway down to Skørping after 2030. The second part of the project deals with the issues associated with a rail connection to Aalborg Airport. The project has investigated the need for a doublerailway track over Limfjorden instead of a singlerailway track. It is concluded that there is no need for expension of the railway bridge over the Limfjorden, because the current capacity is sufficient now and in the future. It will be possible with K13 timetable to align two trains to Aalborg Airport and two trains to Vendsyssel. It is calculated that atleast three trains is needed in 2025, in order to obtain a sufficient amounts of seats for all passengers. However, it is not possible to operater with three trains in Vendsyssel with the current infrastructure. The reason is the current infrastructure north of Lindholm dosen’t fit a 20 min operation schedule. The solution can either be an upgrade to 200 km/h or build new crossings between Brønderselv and Vrå and extend the double track at Sulsted.
