Special Issue Information
Dear Colleagues,
Measurement and monitoring of electrical and electromagnetic quantities in railways has always been an important part of the whole assessment of correct operation of the supply circuit, rolling stock, signaling, and control. The new challenges for sustainable mobility, for impact on third parties, and for high levels of reliability and continuity of service require the development and deployment of new monitoring architectures, integrating various types of smart sensing technologies: Resulting architectures may extend over the entire transportation system, being integrated with the existing infrastructure and exploiting interconnection and data exchange offered by modern communication means, as well as power harvesting.
More traditional applications cover power quality and compatibility with signaling and control systems. Examples of more recent applications range from the monitoring and quantification of the energy efficiency of the whole system (installing sensing units both on-board trains and in supply substations) to fostering predictive maintenance of the current collection system (with existing applications for catenary–pantograph contact quality covering a wide range of physical quantities, with a tendency to integrate modern energy meters with additional monitoring functions). Other applications may focus on the track, monitoring stray current, and corrosion (with challenges of data analysis on different time scales, depending also on the characteristics of the environmental and service conditions), as well as verifying the physical integrity of the track (exploiting existing signaling circuits, or using magnetic, traveling wave or ultrasound excitation).
This Special Issue thus cordially invites contributions on electrical and electromagnetic sensors, smart sensors and measurement, and monitoring architectures for railways.

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. Sensors is an international peer-reviewed open access semimonthly 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 2600 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.
