Railway transport in Russian Federation

• Railway transport in Russian Federation is one of the most important, basic branches of economy. It carries about 80% of freight traffic volume

(without taking into consideration pipeline transport) and about 50 % of the passenger turnover of the transport system of the country.

Objectives of Russian railways in field of international freight traffic development

• Development of international transport corridors

• Development of railway transport as a main link in global logistic chain and deep integration of Russian railways into Euro - Asian transport system.

• Strengthening and development of partnership with countries of 1520 mm gauge and interaction with countries of 1435 mm gauge.

4

Objectives of Russian railways in field of international freight traffic (continuation)

• Working out intergovernmental standards with harmonization of technical requirements and regulations for rolling stock and infrastructure of transport systems

• Development and introduction of prospective rolling stock for freight traffic

• Organizing operation of trains of increased mass and length. Increase in volume of container traffic including intermodal modes of operation.

VNIIZhT objectives in field of freight traffic development (continuation)

• Working out requirements for infrastructure to allow realization of international traffic

• Creation of technologies for operation of trains of increased mass and length

• Technical and technological support for international container and contrailer traffic

• Development of system for automatic identification of rolling stock for 1520 mm gauge area

7

Priorities of Russian railways in field of technical regulation

• Harmonization of norms within

Euro - Asian transport system,

• Achievement of efficient mode of interoperability in different regions, in one region and in combination with other modes of transport,

• Introduction of simplified procedures at border crossings.

8

Maintaining of technical unity withCIS and Baltic states

Legal basis:«Agreement on essential principles of harmonization of technical regulations of the Member States of Euro – Asian economical community” and Draft «Agreement on essential principles of harmonization of technical regulations of Member States of Commonwealth of Independent States”.

9

Maintaining of technical unity with CIS countries and Baltic states (continuation)

• Working out technical regulations in the form of intergovernmental models is required for maintaining unified railway network in CIS countries operating without any technical barriers

10

Harmonization with ЕU

Due to difference in legislative norms, harmonization can be realized by means of coordinating norms, included in the Federal Law (Technical regulations), with by-laws of European Union (Technical specifications for interoperability) or with the standards harmonized with directives

11

Harmonization with EU (continuation)

• In the results of the above, harmonization should be made available exclusively for technical regulation objects which could be operated on Russian and EU infrastructure.

Heavy hauls

In accordance with the decisions and requirements of the JSC “RZD” Programme for Strategic Development, a comprehensive scientific project (CSP) “Increase in mass and length of freight trains on main directions of railway network” has been elaborated by VNIIZhT.

Heavy hauls. Choice of mass of train

An important task – increase in number of trains of increased mass and length, contributes to enhancement of carrying capacity on main directions of railway network and reduction of expenses related to operation of trains.

15

Unified norms of freight train mass

Following parameters for main routes of Russian Railway Network have been approved for the period up to 2010 –2015 as the unified freight train mass norm:

• mass - 6,3 tons, • length - 71 reference cars or 1050 m

16

Trains with mass of 9,0 tons

• Trains with mass of 9,0 tons with traction from head of train and with device for braking synchronization at a train end are used, if necessary, on bulk freight transportation sections

• Main task - to provide the passing of such trains and to ensure the safe operation

• Owing to it, additional economy in terms of locomotives, locomotive crews and power consumption is achieved

17

Trains with mass of 12,6 tons

• If necessary trains with mass of 12,6 tons can operate on railway directions at unified mass norm of 6,3 tons, especially, during summer track maintenance activity or in case of accelerated freight traffic due to emergency

Strengthening of infrastructure

• VNIIZhT has worked out methodology incorporating design and experimental methods for determination of measures required for strengthening infrastructure with regard to introduction of trains operation of increased mass and length. Following issues are under consideration:- systems of traction power supply,- C & S devices,- systems for maintenance of locomotives and cars,- extension of station tracks,- strengthening of permanent way.

Cars of increased load capacity

One of the important directions of the development of heavy haul operations is increase in the car fleet by means of introduction of gandola cars with Tpr clearance gauge. Tpr clearance gauge is 150 mm wider than 1 – T clearance gauge. Height of its rectangular part is 4500 mm, which is 500 mm more than that of 1-Т clearance gauge. In this case, axle load of 25 t is available at the load per meter of 9.5 t/m and it is possible to make-up a train with the mass of about 8,5 tones, axle load of 25 t, consisting of 86 cars on the tracks, length of which is 1050 m. This direction is an alternative to extension of tracks for more than 1050 m.
