Construction of high embankments has become inevitable with the development of railway transportation. The present study investigates the effect of geocell and geogrid layers on controlling the stability and settlement of high railway embankments using laboratory model tests. Five series of embankments with 25cm height were constructed, at a scale of 1:50 and then uniformly loaded on the crest in a loading chamber of dimensions 90 x 90 x 60 cm. The embankments of the first series were constructed without reinforcing layers followed by second to fifth series with one to four layers of reinforcement respectively. The load-settlement results were compared and failure mechanism is studied. When compared to the unreinforced case, there is a significant increase in bearing capacity and decrease in settlement with definite increase in geocell and geogrid layers. But increasing the number of geosynthetic layers beyond the third layer does not make much difference in bearing capacity and settlement. The overall study showed that geocell produces a higher improvement in bearing capacity of 7% and reduction in settlement of 12% than geogrid.
