In 2019 the modern high-tech rail buses RA-3 were purchased for suburban railway routes.
RA-3 railbuses top out at 120 kilometers per hour. It consists of 2-6 cars. Rolling stocks is in accordance with safety requirements and comfortable for passengers.
Rail buses run in three directions: Yuzhno-Sakhalinsk - Korsakov, Yuzhno-Sakhalinsk - Tomari and Kholmsk - Tomari.
At the second stage of the project, 3 more rolling stocks will be purchased, which will allow replacing locomotive traction on the routes Yuzhno-Sakhalinsk - Tikhaya, Tikhaya - Poronaysk, Poronaysk - Pobedino.
As a result, the rolling stock of the suburban traffic on Sakhalin will be completely updated. Modernization of the car fleet will improve the quality of suburban traffic, replace inefficient locomotive traction in suburban traffic in the north of the island, and reduce the cost of repair and maintenance of the car fleet up to 4 times. At the same time, tariffs for the passengers will not change.
