Intermodal Freight Transport in Norway - A Study of Terminals and Railway Performance Time
Malvik, Marie Husum (Master thesis, 2021)Sammendrag Denne oppgaven omhandler planlegging og drift av godstransport og terminaler for omlasting mellom veg og jernbane, et dagsaktuelt og interessant tema. Det er forventet en økning i person- og godstransporten ... -
Investigation of Railway Switch and Crossing with 35 Tonnes Axle Load
Brittmark, Øystein Kleppe (Master thesis, 2021)Økning av volum og vekt av godset som transporteres på tungtransport jernbanelinjer er en måte å øke kapasitet og kostnadseffektiviteten. I tillegg har økt aksellast innvirkning på dynamiske krefter og laster. Ytelse og ... -
Mulighetsstudie av reduksjon av tverrsnittsstørrelsen til jernbanetunneler med hensyn på kostnader og miljø
Moe, Britt Karin (Master thesis, 2021)Det har vært en økning i tverrsnittsstørrelsene til jernbanetunneler i tråd med den teknologiske utviklingen, fra de første togene begynte å kjøre på skinner i Norge. Økningen i tverrsnittsstørrelsen kan forsvares med økt- ... -
Numerical Simulation of Switch and Crossing Towards an Optimized Turnout Design
Lau, Albert (Doctoral theses at NTNU;2018:210, Doctoral thesis, 2018)Switch and crossing (S&C) or turnout is a mechanical component within railway infrastructure that provides flexibility for train to switch from one track to another. However, such flexibility requires certain degree of ... -
Quantm som erstatning for tradisjonelle linjevalgsmetoder
