Chabahar-Zahedan rail link is finally ready: A quiet breakthrough for India’s Eurasian connectivity

For years, the Chabahar-Zahedan railway existed more as a line on strategic maps than as steel on the ground. That changed this month. Iran has completed construction of the roughly 730-kilometre rail link connecting its deep-water Chabahar Port on the Gulf of Oman to Zahedan, the gateway to its national railway network. The line is expected to become fully operational within the next three to four months after final safety checks and commissioning.

This is not just another infrastructure update. For India, it closes a critical missing link in its long-term effort to reach Afghanistan, Central Asia, and beyond — without relying on Pakistan.

What exactly has been built

The railway features 33 stations, 39 tunnels, and 201 bridges across the challenging terrain of southeastern Iran. Once operational, it is designed to handle around 7.7 million tonnes of freight and 2.2 million passengers annually. Freight trains are expected to run at up to 90 km/h and passenger services at higher speeds.

Importantly, Zahedan was already connected to Iran’s wider rail system. Completing the southern stretch from Chabahar means cargo landing at the Indian-operated Shahid Beheshti terminal can now move directly onto the Iranian rail network and, from there, northwards toward Afghanistan and Central Asia.

Why this matters for India

India has invested significantly in Chabahar since the mid-2010s, primarily to create an alternative trade route to Afghanistan and the landlocked Central Asian republics. The port has already handled Indian humanitarian aid and commercial cargo, but the absence of a reliable rail connection limited its scale.

With the railway in place, Indian goods can move from western Indian ports to Chabahar by sea and then continue inland by rail, bypassing Pakistan entirely. This is strategically valuable. It reduces dependence on longer maritime routes and offers Central Asian countries their shortest access to the Indian Ocean.

The project also strengthens the International North-South Transport Corridor (INSTC), the multimodal network linking India to Russia and Europe via Iran. While Chabahar is not the only Iranian port in the INSTC, its location outside the Strait of Hormuz and its growing Indian operational role give it particular importance.

A Long and difficult journey

The idea is not new. Discussions around connecting Chabahar to Iran’s rail network date back more than a decade. India and Iran signed key agreements in 2016, and India committed hundreds of millions of dollars to develop the Shahid Beheshti terminal. Progress, however, was repeatedly slowed by geopolitical tensions, US sanctions on Iran, funding constraints, and construction challenges in difficult terrain.

A 10-year agreement signed in 2024 between Indian Ports Global Limited and Iranian authorities gave the port greater operational stability. The completion of the railway now gives that agreement real logistical teeth. India continues to discuss arrangements that would protect its long-term management rights at the port, particularly if sanctions-related complications ease.

Looking ahead

The immediate impact will depend on how quickly the line becomes commercially active and how efficiently cargo moves across borders. Capacity utilisation, customs coordination, and competitive freight rates will decide whether the route becomes a preferred corridor or remains underused.

In the longer term, further northward extensions — toward Mashhad and the Turkmenistan border — could strengthen the eastern arm of the INSTC and deepen India’s economic engagement with Central Asia. For Afghanistan, the line offers a potential alternative to Pakistani ports for trade with the wider world.

There are still challenges. Geopolitics in the region remains fluid, and infrastructure alone does not guarantee trade volumes. But the completion of the Chabahar-Zahedan rail link removes one of the most significant physical bottlenecks that had limited India’s Eurasian connectivity ambitions for years.

For logistics professionals and policymakers watching India’s regional strategy, this is a development worth tracking closely. The tracks are finally in place. The next question is how effectively they will be used.
