## 1.4.2 Investment project underlying the present technical assistance operation 

The project underlying this technical assistance is the Ukraine Railway Modernisation (the “Project”). 

The Project consists of the phased construction of the electrification of the railway line, over a total length of 253 km, comprising the Dolynska – Mykolaiv section (Phase I, over a total length of 148 km, including new high voltage line with 2 substations) and the Mykolaiv – Kolosivka section (Phase II, over a total length of 105 km), together with the modernisation of signalling and telecommunication system in stations and on open lines. 

The Project shall cover the following main investments: 

## Phase I: Dolynska-Mykolaiv section 

a) Track and electrification works, including construction of railroad track; rearrangement of existing railroad tracks; reconstruction of track arrangement at 12 stations - extension of several arrival and departure tracks; reconstruction of 14 crossings; reconstruction and rearrangement of passenger platforms; laying of switches; 

b) New signalling and communication system installation; 

c) High voltage line connection works (including two sub-stations). 

## Phase II: Mykolaiv- Kolosivka section 

a) Electrification works, 

b) construction of 1 overhead crossing instead of railway crossings; 

c) New signalling and communication system installation. 

Electrification works on both sections include supply and installation of catenary material, construction of traction substations; improvement of the line power supply; installation of automatic line block; implementation of electronic interlocking on stations including new cabling; laying of optical fibre cable; protection of communication lines and of gas pipelines; construction of necessary ancillary structures and other auxiliary works. 

New signalling and communication system installation on both sections : to include: microprocessor systems of electrical interlocking for switches and signals at stations; microprocessor systems of automatic blocking at station-to-station blocks; crossing automatic signalling including automatic level crossing gates to be operated by duty officer at railway crossings; microprocessor systems of centralized traffic control and dispatcher’s control providing data to ASK VP UZ-Ye informational system at dispatching section; digital transport communication network on the basis of fibre optic lines; train and station radio communication systems; modern equipment for operational and technical communication system, double fleet loud speaking communication; modern equipment for remote heat control of rolling stock axle boxes. 

The specific works and supplies specified above may change during the implementation of the Project, subject to agreement between the Banks and Ukraine, in accordance with the Finance Contract. 

## 1.4.3 Ukraine Railway Modernisation Project Implementation Timetable 

The Project is divided into two phases and there will be a separate procurement process for each phase. Works relating to Phase I (Dolynska-Mykolaiv) are expected to commence in Q4 of 2021 and be completed by the end of 2024. The implementation of Phase II is expected to begin in 2022 and to be completed by the end of 2024. 

The promoter has separate TA, also NIP financed, to assist with the procurement of works and supervision services. This is expected to complete its services by Q3 2021. 

## Related programmes and other donor activities 

The Consultant is required to liaise closely with the other Donors, in particular with the EBRD, in order to maximize the value of their services and avoid duplication of efforts.
