abstract = {Real-time and continuous monitoring through smart sensors is considered to be the
evolution of traditional track testing, enabling the earlier detection of the main failure modes that
degrade railway tracks. Through carrying out preventive maintenance operations, infrastructure
resources may be optimized, leading to smarter and more sustainable infrastructure. For this reason,
under the larger goal of creating a synergy with various types of sensors for railway tracks, this article
presents a critical review on the di erent, currently available sensors for smart and continuous
monitoring. Specifically, the most appropriate monitoring technologies for each of the main railway
track failure modes have been assessed and identified, thus deriving the advantages and capacities of
each solution. Furthermore, this review presents some of the main experiences carried out to date
in literature by using sensor technologies, such as strain gauges, piezoelectric sensors, fiber-optics,
geophones and accelerometers. These technologies have proven to o er appropriate characteristics
and accuracy for the continuous monitoring of a railway track’s structural state, being capable of
measuring di erent parameters, such as deflections, deformations, stresses or accelerations that
would permit the technical tracking of various forms of degradation.},
