Abstract. The construction of the Amur-Yakutsk railway from the station Bamovskaya to the station Lower Bestyakh was completed in 2017. The construction lasted more than 40 years. The road was built in stages and commissioned to a temporary and regular operation also by stages. The transition from a stage of a working movement to a temporary operation of the road took from three to eight years. The site from Tommot to Nizhny Bestyakh is planned to be commissioned to a temporary operation until 2019. The NeryungriTommot section still has the status of temporary operation. Long terms of the road transfers from a temporary operation to a regular service are connected with stabilization processes at the base and in the earth embankment. High deformability of the embankment is determined by numerous unfavorable engineering and geological processes that occur in the Quaternary sediments, over which more than half of the entire railway embankment is laid. Ensuring operational reliability of railways built in severe natural and climatic conditions and on thick sedimentary soils is very difficult and is probably the main reason for the difficulties of the road’s transfer to a regular operation.
