    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transport services; Intermodal transportation; transport systems; modelling; express transportation;

    Sammanfattning : Express transport services are produced in highly modularised transport systems, a fact that implies that one subsystem can be exchanged for another without causing a need for major changes in other parts of the system. Express goods are not common on a large scale in freight railway transport systems, as those are often not considered reliable enough for time-critical goods. LÄS MER
