Function
A modern metro expanding Istanbul's public transport network
Project Duration
The December 2024 contract sets a duration of 1,440 days, with metro delivery planned by December 2028.
Purpose
Shortening urban journeys and providing safe, environmentally friendly transport.
The 6.2 km, five station Kirazlı Halkalı University Metro starts at Kirazlı Station on the operating M1B Yenikapı Kirazlı line. It intersects existing and under construction lines before terminating at Halkalı University Station, passing through Bağcılar and Küçükçekmece districts.
Architectural and Engineering Details
Fourteen cross passages facilitate safety and maintenance. Station designs consider modern architecture, disability access, passenger comfort and safety standards.
Technologies and Innovations Used
Excavation uses modern TBMs, with intelligent signaling, energy efficient trainsets and fire safety systems.
Special Solutions
The project was planned as an alternative to Istanbul's heavy urban traffic.
Project Stages and Solutions
Construction Stages
01
Twin tube tunnel excavation, 6.2 km
02
Construction of five stations
03
Construction of two crossover structures
04
Construction of one emergency escape shaft
05
Completion of 14 cross passages
06
Integration of electrification, signaling and safety systems
Solutions
Day and night schedules accelerated work beneath dense urban areas. Cross passages ensured safety and operating continuity.
Sustainability
Economic and Social Impact
It will shorten urban travel for tens of thousands of daily passengers.
It will address Istanbul's transport problems by increasing public transport capacity.
Existing M1 line
Fuel and time savings will contribute to the city economy.
Sustainability and Environmental Sensitivity
Construction Period
TBM excavation is planned to minimize environmental impact by reducing vibration, dust and noise.
The excavation management plan directs excavated materials to reuse and filling.
Site energy efficiency measures, including LED lighting and low emission generators, are planned.
Water recovery systems are planned to save water in site activities.
Materials and labor are planned to be sourced mainly locally; reducing carbon footprint and logistical emissions is among our priorities.
Cross passages were planned for construction safety and emergency exits, prioritizing passenger health and safety.
Operational Period
The electric metro will reduce carbon emissions.
Reduced private car use will lower traffic congestion and noise pollution.
Energy efficient trainsets will provide environmentally friendly transport.
Durable infrastructure solutions will reduce maintenance and increase resource efficiency.
Kirazlı Halkalı University Metro connects European Side lines already operating or under construction. Its integration with two different rail systems makes it an important connecting line.
Starting at Kirazlı, the line serves Barbaros, Malazgirt, Mimar Sinan and Fatih before terminating at Halkalı University.
The metro will have capacity for 700,000 passengers daily.
Tunnel excavation uses NATM and TBM methods, with three tunnel boring machines to be used.
Kirazlı Halkalı University Metro connects with the following existing and under construction lines:
M1B Kirazlı Yenikapı Metro at Kirazlı Station,
M3 Bakırköy Kirazlı Başakşehir Kayaşehir Metro at Kirazlı Station,
M9 Ataköy Olimpiyat Metro at Mimar Sinan Station,
Following phase two, Marmaray and Istanbul Airport Halkalı Metro at Halkalı Station.
