Special Issue Information
Dear Colleagues,
Over the last decade, European railway network capacity has experienced a rapid increase, all with the purpose of fulfilling the requirements of the White Paper published by the European Commission, which requested a switch of passenger and freight transportation from road to rail to protect the environment by reducing CO2 emissions and energy savings. By increasing network capacity, the railway tracks that are currently installed and in use are being expected to withstand more than what they were designed for in terms of axle load, train speed, and frequency of passages. As a result, more efficient, effective, and sustainable maintenance is required. Additionally, it is becoming more urgent to conduct economic-based widespread research for cost-effective improvement of rail transport to come up with rehabilitation strategies. To achieve these objectives, which are not only restricted to European network problems, it is necessary to have:
- Reliable dynamic models of railway tracks providing usable numerical results within a reasonable computational time, with acceptable precision and accounting for uncertainty of mechanical properties of railway track components;
- Effective solutions for vibration mitigation;
- Sustainable solutions for transition zones;
- Efficient methods for monitored data analysis to identify critical regions;
- Reliable performance indicators of railway structure to measure the added value of rehabilitation interventions;
- Cost–benefit analysis based on an economic feasibility study adapted to railway problematics in order to identify the most beneficial maintenance strategies.
This Special Issue intends to summarize recent developments in the topics identified above. Other submissions on related topics are also welcome.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Vibration is an international peer-reviewed open access quarterly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
