2. 1. Cost-effective maintenance of railway track geometry : a shift from safety limits to maintenance limits

   Author : Iman Arasteh Khouy; Peter Veit; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance Engineering;

   Abstract : Railway infrastructure is a complex system which comprises different subsystems. Long life span is one of the important aspects of this prime mode of transport. However, the useful life of its assets is highly dependent on the maintenance and renewal strategy used during the assets’ life cycle. READ MORE

4. 2. Predictive Models for Railway Track Geometry Degradation

   Author : Iman Soleimanmeigouni; Alireza Ahmadi; Nalinaksh S. Vyas; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Data-driven models; Degradation; Inspection; Maintenance; Predictive analytics; Tamping; Track geometry; Railway infrastructure; RAMS; Drift och underhållsteknik; Operation and Maintenance;

   Abstract : Railways are a vital and effective means of mass transportation and play a vital role in modern transportation and social development. The benefits of the railway compared to other transportation modes are a high capacity, high efficiency and low pollution, and owing to these advantages, railways are nowadays experiencing a higher demand for the transportation of passengers and goods.

5. 3. Development of life cycle cost model and analyses for railway switches and crossings

   Author : Arne Nissen; Ajit Kumar Verma; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

   Abstract : Infrastructure managers need to have a safe and available infrastructure, so that train operators can deliver a transport product at an affordable price. In the future, as traffic volume increases, higher utilisation of the existing capacity, less time for maintenance and fewer unplanned interruptions will be critical for meeting the ever increasing need of transport capacity.

6. 4. Data-driven predictive maintenance planning and scheduling

   Author : Mahdieh Sedghi; Bjarne Bergquist; Erik Vanhatalo; Ramin Karim; Luleå tekniska universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kvalitetsteknik och logistik; Quality Technology and Logistics;

   Abstract : The railway track network is one of the major modes of transportation and among a country’s most valuable infrastructure assets. Maintenance and renewal of railway infrastructure have a vital role in safety performance, the quality of the ride, train punctuality, and the life cycle cost of assets. READ MORE
