  9. 2. Transportation A. Traffic Movement by Mode Freight : Road 48.8%, Railway 16.7%, Pipelines 28.3%, Seaport 6.1% Passenger : Road 84.0%, Metro 15.3%, Railway 0.6%, Airport 0.1% Freight Transportation Passenger Transportation

  10. 3. Related Plan C. Railway Modernization Program Modernization of the Azerbaijan railway network Improvement of laws, transport capacity, vehicle, facilities, etc. Total project cost : 1,5 bln USD Loan from the World Bank

  11. 1. Alignment A. General It was single track, which was electrified to a double track gauge, and is the main arterial railway of Azerbaijan. It is a broad gauge with 1,520mm and 503km in total length. It has 45 stations. Railway makes a total round trips of 38 times among which 9 and 29 times are for passenger and freight trains respectively. B. Horizontal Alignment Minimum curve radius : R=250m / 1 section Curved section at start point & end point of route (18 section / 41.5km) Field area passage C. Vertical Alignment Maximum slope : 16/1,000 General slope : less than 10/1,000

  12. 2. Roadbed A. Earth work section Although the roadbed status is stable, the water distribution is bad Occurrence of mud-gush and flood at many sections No seriously dangerous sloped surface 4km of poor subsoil near the lake at the outer boundary of Baku B. Bridges Main bridges are Yevlax bridge (L=240m) and Poylu bridge (L=208m) that cross the Kur river Two bridges are through-truss bridge and are in good condition Most of other small bridges also good condition C. Crossings Most of the crossings excluding the area adjacent to Baku are level crossings The number of level crossings are 83 Relatively small transportation volume

  13. 3. Track Gravel ballast & 400m of longer rail Sleeper : PC sleeper 60%, Wooden sleeper 40% Fastening System : K Clip for PC sleeper, Dog Spike for wooden sleeper High track deformation due to deficiency of gravels especially at the turnout area Track materials are aged, damaged and in bad maintenance condition

  14. 4.Electrical System A. Power Supply Railway substation receives electricity of AC 110kV, 35kV, 10kV, and 6kV from the electricity company The traction power supply system is DC 3,300V The power supply system and catenary system are obsolete There is no centrally-concentrated management device for electric power supply It is not advisable to operate railway faster then 80km/h with the current aerial line and electric facility B. Signaling 3 signal aspects with both independent and multi-unit light signals are in use. Rely interlocking system installed in 1923 is still in use With 3-aspect of block signals, ATS type has been applied, permitting a design speed of 120km/h. Each block section is located at a distance of 2~2.6km. The knowledge and information of control staff members are vital factors because there is no CTC.

  15. 4.Electrical System C. Communications The optical fiber cable (16core× SM× 1set) was installed between both tracks Optical transmission equipment and exchanger use the Siemens Hicom 300H The HF SSB type train radios system provides communications between on board-ground and ground-ground There is no Hot-Line Equipment, passenger information system 5. Station 45 stations between Baku and Georgia border Slow operation at the starting point and end point of the stations due to S-curve Poor roadbed due to mud-gush and pumping phenomena

  16. 6. Overview of Survey Result of Survey Good alignment in general as a straight line running through plain fields Bad drainage in roadbed, continuously weakening subsoil Bad alignment deformation due to the old track facilities and bad maintenance Bad maintenance and aging for electricity supply facility Possible to operate 120km/h train with ATS signal system but facilities are outdated Synthesized valuation Looking at the overall investigation result of the facility condition of the existing railway, facilities are outdated in general and need to be replaced, and it is impossible to operate railway faster than 80km/h.

  17. A. Comparison/investigation by service level Total service with the max. speed of 140km/h Securing of optimal track conditions and provision of all services including passengers' convenience, station automation, etc. Alignment improvement of the curved sections of 41.5km in the downtown of Baku and near the border to Georgia Change of the power supply system from DC to AC and overall improvement of the roadbed, track, railway's electric facilities, etc. Basic service with the max. speed of 140km/h Reduction of the project cost by minimizing service such as passengers’ convenience, station automation, etc. if not affecting the safe operation of trains Partial improvement of the roadbed, track, railway's electric facilities, etc. Change of the power supply system from DC to AC

  18. Replacement of existing facilities No separate improvement of the roadbed by earth work and double track of Poylu bridge which is currently a single track bridge (construction of an Additional bridge) Track improvement of the entire section except already-improved 75km-long section [including accessory signaling/communications] Change of the power supply system from DC to AC B. Proposal of improvement plan by service level Reflection of the function in the TAR line Proposal of the replacing existing facilities as the optimal improvement plan

  19. 1.Alignment A. Horizontal alignment Not necessary to improve alignment if limiting the operation speed of trains in the 41.5km section with curved alignment at the start/end section in Baku~Beyuk Kesik line B.Vertical alignment Maximum slope of 16/1,000 exists in the Zarat~Giazi, which is a short section In general slopes are less than 10/1,000, enabling an operation of 150km/h trains 2.Roadbed A. Earth work section Securing of bearing capacity by compacting the mud gush level after replacing with quality roadbed material when replacing ballast gravels Securing of smooth drainage by constructing a 3% slope for drainage on the upper roadbed of the main track B. Bridges Partial maintenance including painting and crack repair of existing bridges, is required. Additional construction of a new single track bridge is required. Poylu bridge is to be double tracked, which is a single track bridge, now

  20. 3.Track Replace / Improve the existing track facilities except for 75km that has been improved Apply PC sleepers to the gravel ballast Upgrade the fastening system to Vossloh System W14 Increase resistance and elasticity of roadbed against the increased speed Support of continuity with the section currently maintained for the track by importing the rails from Russia The sleepers are to be supplied from a sleeper factory near Alat station. But required to examine its expansion after checking its supply according to construction plan by stage. For gravel, production and use of crushed stone by inputting stone breakers in the quarries near Ganja and Kavkaz shall be made

  21. 4.Electrical system A. Power supply Catenary power supply shall be changed from DC supply system to AC 25kV system. Establishment of remotecontrol facilities for the power supply system to the contact wire line Double trolley Simple catenary Pole to be installed with economically-profitable concrete poles Use 2 distribution lines, one of power supply facilities which are used for signal and station, and apply a method of supplying AC 6.6kV or AC 10 kV B. Signaling For economic efficiency and convenience of maintenance, ground-based signal is preferred to on-board signal and thus ground-based signal(5 aspects) is adequate. Because fixed and automatic block system are enough for maximizing transport capacity and guaranteeing safe operation in sections of 150km/h speed limit, fixed and automatic block system, which also cost less, are selected. Electronic interlocking system, which makes it easy to trace train, manages train diagram, and modifies and expands facilities in accordance with program, is used.

  22. 4.Electrical System C. Communications Construct dual optic-fiber networks for signal and remote control of electric facilities and accompanying conduit and transmission equipment. Installation of traffic control telephone system to support traffic control Existing train radio system to be reused 5.Station For the mud gush level, required to do same replacement and compaction as the improvement of the main track's roadbed is needed to secure bearing capacity Required to examine the installation of such drainage facilities inside a station as the U-type gutter and collection tank for drain are required

  23. 3. Proposal for railway improvement Necessity of construction plan by stage The scope, project cost, period, train operation of the improvement project as a long distance line are considered. Required to promote the project according to priority by considering the maintenance conditions of facilities Consideration of the efficiency of train operation during work according to the change of power supply system into AC Connection between adequate financing plan of the project cost and the Government's financial conditions and other economic situations Faithful execution of the Railway Modernization Program - Change of the power supply system from DC to AC - Introduction of the electric locomotive only for AC Improvement plan • Improvement by • sectional priority B. Improvement by a priority by type of work
