We present the application of a Brillouin distributed sensor for railway traffic monitoring. The field test is performed on the Italian regional line San Severo - Peschici. A single-mode optical fiber was attached along a rail length of about 60 meters. The strain associated to train passage was acquired along the monitored rail length, at 31 Hz acquisition rate and 1-m spatial resolution. The sensor is capable to retrieve useful information in railway traffic monitoring, such as train identification, axle counting, speed detection, and dynamic load calculation.

Abstract
We present the application of a Brillouin distributed sensor for railway traffic monitoring. The field test is performed on the Italian regional line San Severo - Peschici. A single-mode optical fiber was attached along a rail length of about 60 meters. The strain associated to train passage was acquired along the monitored rail length, at 31 Hz acquisition rate and 1-m spatial resolution. The sensor is capable to retrieve useful information in railway traffic monitoring, such as train identification, axle counting, speed detection, and dynamic load calculation.File in questo prodotto:
