A monitoring cable includes an outer jacket having a generally rectangular cross-sectional profile. The monitoring cable further includes a strain monitoring unit disposed within the outer jacket, the strain monitoring unit including a plurality of optical fibers embedded in a potting layer. The monitoring cable further comprises a protective unit disposed within the outer jacket and spaced from the strain monitoring unit, the protective unit including an optical fiber disposed within a metal outer jacket. A method for monitoring a rail track includes attaching a monitoring cable to the rail track. The method further includes monitoring strain of the rail track by measuring movement of the optical fibers of the strain monitoring unit.
