dynamically exchanging energy during so-called regenerative braking. This kind of simulation helps to optimize
train patterns for stray current reduction, but also to
identify hot spots on which to target the necessary countermeasures (see Figure 8).

J. Bongiorno (jacopo.bongiorno@edu.unige.it) received his
B.A. and M.S. degrees in electrical engineering in 2012
from the University of Genova, Italy, and is currently pursuing a Ph.D. degree in electrical engineering. He worked
as a grant holder in national and international research
programs. His research interests are the modeling and
testing of electrical and power systems (in particular, electric transportation systems) and the related activities of
verification and validation of simulation models.
G. Boschetti (girgio.boschetti@gmail.com) received his
B.A., M.S., and Ph.D. degrees in electrical engineering from
the University of Genova, Italy, in 2007, 2010, and 2013,
respectively. During his Ph.D. work, he gained experience
with the modeling and simulation of electric transportation systems and energy optimization strategies for mass
rapid transit systems, working in national and international research programs. He is currently working as a grant
holder at the Department of Naval, Electrical, Electronic,
and Telecommunication Engineering, University of Genoa.
A. Mariscotti (andrea.mariscotti@astme.ch) received a
degree (cum laude) in electronics engineering in 1991 and
a Ph.D. degree in electrical engineering in 1997 from the
University of Genova, Italy. From 1998 and 2004, he
worked in national and international research programs
as a tenured researcher supported by different grants.
Since 2005, he has been an assistant professor in the former Electrical Engineering Department of the University
of Genova. Presently on sabbatical leave, he cofounded
ASTM Analysis, Simulation, Test, and Measurement Sagl,
a company that is active in the electromagnetic and electrical compatibility sector and performs analysis and
tests and manufactures instruments. His main research
interests are electromagnetic compatibility applied to
industrial, military, and transportation systems; modeling
and measurement of electromagnetic interference and its
relevance to safety and availability; and the design and
construction of measurement instruments. He is also a
reviewer for IEEE transactions and journals, Elsevier, and
the Institute of Physics and Springer. He is a registered
professional engineer in the province of Genova. He is a
member of the IEEE Instrumentation and Measurement
Society and the Italian Electrical and Electronic Measurement Group and is a Senior Member of the IEEE.
