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 120 km/h. Each block section is located at a distance of 2~2. 6 km. The knowledge and information of control staff members are vital factors because there is no CTC. Interlocking

4. Electrical System C. Communications The optical fiber cable (16 core× SM× 1 set) was installed between both tracks Optical transmission equipment and exchanger use the Siemens Hicom 300 H 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 Optical fiber cable connection box 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 S-Curve in station

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and aging for electricity supply facility Possible to operate 120 km/h train with ATS signal system but facilities are outdated Synthesized valuation Looking at the overall investigation result of the facility condition of the existing railway, facilities are outdated in general and need to be replaced, and it is impossible to operate railway faster than 80 km/h.

A. Comparison/investigation by service level Total service with the max. speed of 140 km/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. 5 km 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 140 km/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

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 75 km-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

1. Alignment A. Horizontal alignment Not necessary to improve alignment if limiting the operation speed of trains in the 41. 5 km 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 150 km/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

3. Track Replace / Improve the existing track facilities except for 75 km that has been improved Apply PC sleepers to the gravel ballast Upgrade the fastening system to Vossloh System W 14 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 Fastening system Vossloh system W 14
