General states
The strategy of development of railway transport in
the Russian Federation up to 2030 envisages
increasing amount of freight traffic by about 40%. One
of the objectives is to bring between overhauls tonnage
by 2015 to 1.5 billion tonnes gross, and by 2030 to 2.5
billion tonnes gross. To achieve these parameters is
necessary to develop more sophisticated design
elements of the track’s permanent way.
When choosing the design of the way the main
criteria are the cost and duration of the life cycle.

Scheduled for future track network of
OJSC "Russian Railways" with heavy
haul, fast and high-speed traffic
New high-speed tracks for passenger
400 km/h
traffic with speeds up to:
Combined traffic high-speed
Passenger - 250 km/h
tracks with trains speed up to:
Freight - 90 km/h
Fast tracks with combined traffic,
including heavy haul, with trains speed:

Passenger from 160 to
200 km/h
Freight up to 90 km/h
Comparison of change in length of track with continuous welded rails by year
on Siberian and Far Eastern railways and on the network as a whole
The area in which continuous welded rails has been laid is increasing and it currently
accounts for 67.1% of the total length of railway network’s main lines.

Operational conditions on Russian railways
The Russian Federation is characterised by a variety of building and
operating conditions
Depending on their geographic and climatic location, construction
zones are defined:
- according to the relief conditions – from plains to mountainous areas
- according to geological factors – from swampy land to rock
foundations
- according to type of climate – from subtropical to Arctic.
Maximum daily temperature range: 40°С
Maximum annual temperature range: 120°С
Number of days per year with temperature < 0°С: 221.1.
Occurrence of snowstorms and snowdrifts.

Polyurethane coating is applied to the surface of the ballast and
prevents it from being moved by air wave created by the passage of
high-speed trains.

Conclusions
1. The main criterion in selecting a track design is the cost and the
length of the life cycle.
2. The main track design on Russian railways, including those in
Siberian areas, is continuous welded rail on reinforced concrete
sleepers.
3. Railway track in Russia is operated in difficult climatic, engineering
and geological conditions which are taken into account in the
selection of the parameters for building and fitting track.
4. The main objective is to reduce costs for the rail clips. This is
priority way for cooperation.
5. Integrated measures have been carried out to lengthen the
service life of the rails to 1.5 billion tonnes gross.
