Introduction
The Chelyabinsk Metrotram is a light rail rapid transit system serving the industrial and residential districts of Chelyabinsk, a city located in the southern Urals of Russia. Designed to bridge the capacity and speed gaps between conventional tram networks and heavy metro lines, the Metrotram system incorporates features of both transit modes, offering high-capacity, high-frequency service with dedicated rights‑of‑way in key corridors. The project, conceived in the early 2000s, reflects the city’s commitment to modernizing its public transport infrastructure and reducing traffic congestion and air pollution in the region.
History and Planning
Early Transport Context
Chelyabinsk’s public transport history dates back to the late 19th century when horse-drawn trams first appeared. The 20th century saw the introduction of electric trams in the 1920s, followed by a rapid expansion of the network during the Soviet era. By the 1990s, the city’s tram system, comprising numerous lines and a dense network of stops, had become a backbone of daily commuting. However, the growth of automobile ownership and the expansion of urban districts exposed the limitations of the legacy network, particularly in terms of capacity, speed, and reliability.
Conceptualization of the Metrotram
In response to these challenges, city planners and regional transportation authorities initiated a study to determine the most effective solution for enhancing transit service. The study concluded that a Metrotram, combining tram flexibility with metro performance, would best meet the city’s needs. The concept was officially adopted in 2001, and the first detailed design phase began in 2003.
Construction and Inauguration
Construction commenced in 2006 on the first phase of the Metrotram, focusing on a 12.5 km stretch between the central transport hub in the city centre and the industrial zone in the south. The project involved the following major milestones:
- 1999–2001 – Feasibility studies and environmental assessments
- 2001–2003 – Design and procurement of rolling stock
- 2006–2009 – Civil engineering works, track laying, and station construction
- 2009 – First trial runs and safety certification

Route and Stations
Main Corridors
The Chelyabinsk Metrotram network is divided into three primary corridors:
- Central–Industrial Corridor: Links the downtown core with the southern industrial district.
- East–West Connector: Provides cross‑city service between the eastern residential areas and the western suburbs.
- North–South Loop: Serves the northern industrial zones and southern commuter suburbs.
Each corridor incorporates both dedicated right‑of‑way segments and shared roadway sections, allowing for efficient use of existing urban infrastructure.
Key Stations
Below is a non‑exhaustive list of major stations along the network, along with notable characteristics:
- Central Station – The primary interchange hub, adjacent to the city’s main bus terminal and metro line.
- Industrial Park – Serves a large manufacturing complex, featuring a large parking facility for employees.
- University Station – Located near the Chelyabinsk State Technical University, designed to accommodate high student traffic.
- Greenbelt – A station with integrated park and ride facilities, encouraging commuters to transition from car to tram.
- Westbound Terminal – The terminus of the West–East corridor, featuring a maintenance depot and storage tracks.
All stations are equipped with modern security systems, including CCTV, emergency call points, and public address systems.
Operations and Management
Service Frequency
During peak hours (7:00–9:30 and 16:00–18:30), trains operate at intervals of 3 minutes, providing rapid service for commuters. Off‑peak and weekend schedules maintain 6–8 minute headways, balancing operational costs with passenger demand.
Fare Structure
The fare system is zone‑based, with a base fare of 15 rubles for a single trip within the central zone. Integrated ticketing allows transfers between the Metrotram, conventional tram lines, and city buses without additional charges. The system supports single‑use tickets, day passes, and multi‑day travel cards, all purchasable via vending machines or a mobile application.
Management Organization
Operations are overseen by the Chelyabinsk City Transport Authority, a municipal department responsible for scheduling, maintenance, and customer service. The authority collaborates with the Ministry of Transport and local universities for research and development initiatives aimed at improving service efficiency.
