GC NPS, JSC companies have built a new passing loop on the BAM.

To expand the railway by 2.4 kilometers, builders prepared an embankment and constructed one bridge and one culvert at water crossings.

The railway section's alignment traverses boggy marshland and areas of permafrost. To reinforce the roadbed foundation, the embankment slopes were covered with a protective layer of large stones to provide cooling.

At the passing loop, pneumatic switch heating systems have been implemented, and 15 high-voltage power line supports have been installed to power the facility. Train operations are governed by the MPC-EL microprocessor-based interlocking system, a product of GC NPS, JSC companies' R&D and manufacturing capabilities.

The single-track section between Marevaya and Zmeyka constituted a capacity constraint on the Tynda-Dipkun railway line prior to the construction of the passing loop. The establishment of the passing loop, in combination with the introduction of other infrastructure assets, will facilitate an increase in the throughput capacity of this section of the Baikal-Amur Mainline (BAM) from 25 mln to 35 mln tpa.
