Due to the procedure of increasing in axial load and speed on the existing railway tracks, need of improvement will be felt over the embankment. In this regard, one of the techniques is the use of geocell in the process of upgrading rail tracks. Therefore determination of the number of geocell's layers and alignment of their positions has a key role in this issue. Since influence of the number of layers and geocell's specifications on stability control and railway embankments' settlement are not specifically discussed in the technical literature, in this paper, by construction and loading of six embankments with m height in laboratory scale of , the influence of the number of geocell's layers with aperture size of
without any geocell had an increasing of 86.6\% and a decreasing of 37\% over embankment's crown, respectively. In all tests circular sliding surface was superficial \& cutted the embankment at the top of slope that result in horizontal cracks at the levels of first \& second layers over the embankment's slope.
