Sofia - Bulgaria
The Metropolitan JSC Sofia network consists of three metro lines that branch out towards the periphery and intersect centrally in a triangular layout. Upon completion of the planned extensions, the metro system will span a total length of 65 km and include 60 stations. The first two metro lines are equipped with standard metro systems and are powered by a contact ground rail. In contrast, the third metro line features a distinct power supply system: in tunnel sections, it uses a rigid contact network, while in open sections, it utilizes an overhead contact wire. This third line operates as a stand-alone system, separate from the existing metro routes.
The third metro line represents a new generation of metro systems, featuring advanced technologies such as third-generation automatics (Gao3), platform screen doors for enhanced passenger safety, and automated traffic control. Additionally, this line is equipped with a Communication-Based Train Control (CBTC) system, marking a significant advancement in rolling stock automation. A new Automatic Train Control (ATC) system has also been implemented, ensuring the highest levels of safety throughout the line, including operations within the depot.
While the station layouts constitute only about 2.5-3% of the project’s overall cost, they play a crucial role in enhancing passenger experience. Each station was designed with modern architectural solutions, tailored to create comfort and shape the metro’s image.
The construction of the third metro line is part of the “Transport and Transport Infrastructure” Operational Program for the 2014-2020 period. Construction began in January 2016 and was divided into three stages. Currently, after completing stages 1 and 2, the Sofia metro covers 52 km with 47 stations, serving an estimated 400,000 passengers daily and transporting over 100 million passengers annually.
This project aims to enhance the Sofia Metro’s ability to adapt to fluctuating passenger demand through the adoption of new technologies and digitalization. Improved coordination with other transport modes and new mobility services will further increase its efficiency. The Sofia Metro’s involvement in a comprehensive study, including customer profiling, will enable improvements in travel conditions and metro car design, ensuring they meet the diverse needs of passengers.
