Current Collection Quality Solutions in Electric Trains

Dear Colleagues,

In electric rail transportation, the equipment used for transmitting the electric energy to the train is called the current collection system. The traditional method involves the use of the pantograph–catenary system, in which the pantograph, mounted onto the train roof, collects the current from the catenary erected along the track. The third shoe rail and rigid catenary–pantograph systems are the widely used replacements for urban rail transit. All of these approaches rely on sliding contact to realise electric transmission to the electric train from the power supply, raising both mechanical and electrical issues. With the expansion of rail transit around the world, the study of the current collection quality of electric trains has attracted ever-increasing attention from both the academic and industrial communities. Indeed, it is essential that we enable the faster and more reliable operation of electric trains, contribute to minimising incidents that cause traffic disruptions and reduce the maintenance costs of the rolling stock and infrastructure. In this context, we are pleased to announce this Special, entitled “Current Collection Quality Solution in Electric Trains”. Possible topics include, but are not limited to, the following:

• pantograph–catenary interaction;
• vehicle–grid system;
• current collection quality;
• maintenance of current collection system;
• design and optimisation of the current collection system;
• third shoe rail system;
• contactless power supply in rail transit.

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. Vehicles 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.
