The Trans-Iranian Railway: A Testament to Engineering and National Pride
The Trans-Iranian Railway, inscribed as a UNESCO World Heritage Site in 2021, stands as a remarkable testament to engineering prowess, national resilience, and the spirit of collaboration. This expansive railway network stretches across 1,394 kilometers, connecting the Caspian Sea in the northeast with the Persian Gulf in the southwest, traversing diverse landscapes and climates.
More to come…UNESCO Description of the World Heritage Site
The Trans-Iranian Railway connects the Caspian Sea in the northeast with the Persian Gulf in the southwest crossing two mountain ranges as well as rivers, highlands, forests and plains, and four different climatic areas. Started in 1927 and completed in 1938, the 1,394-kilometre-long railway was designed and executed in a successful collaboration between the Iranian government and 43 construction contractors from many countries. The railway is notable for its scale and the engineering works it required to overcome steep routes and other difficulties. Its construction involved extensive mountain cutting in some areas, while the rugged terrain in others dictated the construction of 174 large bridges, 186 small bridges and 224 tunnels, including 11 spiral tunnels. Unlike most early railway projects, construction of the Trans-Iranian Railway was funded by national taxes to avoid foreign investment and control.UNESCO Justification of the World Heritage Site
Criterion (ii): The Trans-Iranian Railway is the living manifestation of the multi-faceted interchange of human values, represented by the application of railway skills and experience in railway construction, leading to the emergence of a mixed Iranian-Western architectural style. The Trans-Iranian Railway boosted the economy and trade by speeding up transportation, which led to the revival of cultural-historical routes such as the Silk Road and the Spice Route at a specific period in the contemporary history in Central and West Asia during the early 20th century. This practice was later expanded to European countries. The Trans-Iranian Railway also served to connect the Persian Gulf to the Caspian Sea. In addition, at the time it was built, the Trans-Iranian Railway promoted exemplary project management, which was achieved as a result of the successful working relations established between the Iranian Government, the project managers and the 40 Iranian or international companies established in 43 construction zones en route with a totally deployed work force of over 65,000 engineers, office staff members and labourers. Located in a mountainous landscape, the Trans-Iranian Railway proved an outstanding tool for solving unexpected problems, an achievement owing to the international breadth of experience that was applied in its construction, enabling the Trans-Iranian Railway project, overall, to stay on time and on budget.
Criterion (iv): The Trans-Iranian Railway is a fine example of a technological and architectural ensemble representing major stages of long-term development of human, technical and economic activities as early as the 20th century, in Western Asia. It played a unique role in the modernization of Iran. This role was firstly maintained through the function of the Trans-Iranian Railway in importing and domesticating western technologies, and secondly through national financing, enabling and also managing construction activities and their implementation, and finally through its unique impact on the country's social, economic, and cultural spheres. It has also caused a huge increase in trade, and cultural and economic relations between different regions within Iran and between Iran and other countries of the region. Thus, it has marked a significant and decisive stage in the process of the historical development of Iran and other countries of the region. This altogether paved the way for later communication and transportation activities with many parts of the world. The Trans-Iranian Railway is the embodiment of the creative usage of various technologies aimed at gaining access to plains, highlands, forests and coastal regions at both ends of the country and linking the northern and southern shores of Iran.
Encyclopedia Record: Trans-Iranian Railway
The Trans-Iranian Railway was a major railway building project started in Pahlavi Iran in 1927 and completed in 1938, under the direction of the then-Iranian monarch Reza Shah. It was entirely built with indigenous capital, and links the capital Tehran with Bandar Shahpur on the Persian Gulf in the south and Bandar Shah on the Caspian Sea in the north, via Ahvaz and Ghom. In 1961, under Reza Shah's son Mohammad Reza Pahlavi, it was extended from Bandar Shah to a new terminus in Gorgan. During the land reforms of Mohammad Reza Pahlavi in 1963, as part of the "White Revolution", the Trans-Iranian railway was extended to link Tehran to Mashhad, Tabriz and Isfahan.Additional Site Details

Mikaya Koyagi. Iran in Motion: Mobility, Space, and the Trans-Iranian Railway.
The Trans-Iranian Railway is reimagined through the lens of mobility and spatial transformation in Mikaya Koyagi's Iran in Motion. The book argues that the railway's construction during the late 19th century was not merely an engineering feat but a catalyst for profound socio-spatial changes across Iran. Koyagi employs a multidisciplinary approach, integrating historical analysis with spatial theory to demonstrate how the railway reshaped regional connectivity, economic landscapes, and cultural identities. The study challenges conventional narratives by emphasizing the railway's role in creating fluid, dynamic spaces rather than fixed geographical boundaries.

Iran in Motion: Mobility, Space and the Trans-Iranian Railway by Mikiya Koyagi
Iran in Motion: Mobility, Space and the Trans-Iranian Railway by Mikiya Koyagi reveals that the Trans-Iranian railway network, constructed under Shah Mohammad Reza Pahlavi’s regime, facilitated diverse mobilities and subjectivities beyond the state's initial intentions. The study demonstrates how technology transfer adapted to Iran's evolving needs reshaped national space and societal dynamics in the 20th century. By integrating historical analysis with mobility studies, Koyagi explores the railway's socio-political impact, highlighting its role in creating new forms of movement and identity. While the empirical evidence primarily focuses on elite perspectives, the book effectively theorizes the unintended consequences of railway-induced mobilities, particularly in religious pilgrimage contexts.

Iran in Motion: Mobility, Space, and the Trans-Iranian Railway
A transnational and decentralized history of the Trans-Iranian Railway (TIR) reveals its complex role in shaping Iranian sovereignty, mobility, and nation-building. Unlike colonial railways, the TIR was built by a sovereign national government, funded through state monopolies rather than loans, and resisted British proposals for east-west routes to counter Russian influence. The study highlights the railway's uneven impact on local communities, including tribal areas like Lorestan, where employment opportunities facilitated pacification while creating interdependent relationships with the Pahlavi state. Additionally, it underscores the TIR's global significance during World War II as a critical link in the Lend-Lease program and its role in facilitating transnational movements of both communist revolutionaries and Shiʿi pilgrims. This approach challenges methodological statism in Iranian historiography by integrating local, regional, and international perspectives.

Iran in Motion; Mobility, Space, and the Trans-Iranian Railway, by Mikiya Koyagi
A groundbreaking analysis reveals the Trans-Iranian Railway as a pivotal agent of spatial transformation, reshaping Iran's economic and social landscapes during its construction (1890–1940). Mikiya Koyagi demonstrates how this infrastructure project, spanning 1,300 km from the Caspian Sea to the Persian Gulf, accelerated mobility while simultaneously reinforcing colonial power dynamics. The study employs a multi-scalar approach—combining archival records, engineering documents, and ethnographic observations—to uncover how railway expansion redefined regional connectivity, labor systems, and state formation in early 20th-century Iran. Koyagi's work challenges conventional narratives by framing the railway not merely as a technological achievement but as a catalyst for contested spatial practices that continue to influence Iran's development.

The Vernacular Journey: Railway Travelers in Early Pahlavi Iran, 1925–50
Railway travel in early Pahlavi Iran (1925–50) was not a unifying experience but a fragmented one, reflecting the diverse social, cultural, and ethnic divisions of Iranian society. Middle-class travelers used the railway space to assert their class identity while distinguishing themselves from others, driven by a desire for a homogeneously Europeanized nation. The study analyzes how journalists constructed the railway traveler as a symbol of modernity before 1938 and how, in the 1940s, the railway became a microcosm of Iran's heterogeneity, compelling travelers to seek national cohesion through extensive travel. It combines discourse analysis with spatial practices to reveal the complex social dynamics of early Iranian railway culture.
