ML-1 Project Explained: The $6.6 Billion Railway Upgrade
Pakistan Railways' biggest modernization in decades starts from Karachi Port in 2026. Here's what it actually is, and what it changes for you.
Quick Answer
ML-1 is a full modernization of the 1,726 km Karachi-to-Peshawar railway mainline — the corridor that carries most of Pakistan's rail traffic. It's estimated to cost around $6.66 billion, down from an earlier $9 billion figure, with construction on the first phase (Karachi-Rohri, ~480 km) targeted to start from Karachi Port in July 2026 and complete within roughly three years.
What Is Main Line 1, and Why Does It Matter?
Pakistan Railways' network is organized around a handful of trunk routes, and ML-1 — Main Line 1 — is the most important one by far. It runs from Karachi on the coast, up through Rohri, Multan, Lahore, and Rawalpindi, all the way to Peshawar near the Afghan border. If you've ever ridden the Green Line, Tezgam, Khyber Mail, or Karakoram Express for any real distance, you've traveled on ML-1.
The problem is that large stretches of this corridor are still single track, with signaling and civil infrastructure that predates independence in many segments. That caps how many trains can run per day, how fast they can go, and how much freight can move alongside passenger services. ML-1 is the plan to fix all three at once.
What Actually Gets Built
Track Dualization
Converting single-line stretches to double track so trains in opposite directions don't have to wait for each other at passing loops.
Modern Signaling
Replacing manual and semi-automatic block signaling with modern systems that allow tighter, safer train spacing.
Freight Capacity
Heavier axle loads and better yards near Karachi's port, letting more cargo move by rail instead of truck.
Higher Speeds
Rebuilt track geometry and bridges designed to safely raise maximum operating speeds above today's limits.
The Phased Rollout
ML-1 isn't a single construction project — it's being broken into five phases so that funding, contractors, and disruption to running trains can be managed one segment at a time. The first and most advanced phase covers roughly 480 kilometres between Karachi and Rohri, carrying an estimated $2 billion price tag on its own, with physical work beginning from Karachi Port and a completion target of about three years from groundbreaking.
Construction starting from Karachi Port, July 2026. Roughly $2 billion. ~3-year target.
Cover the remaining corridor through Multan, Lahore, and Rawalpindi up to Peshawar, planned to follow in subsequent stages as financing and design are finalized.
Who's Paying for It?
ML-1 began life as a flagship project under the China-Pakistan Economic Corridor (CPEC), and Chinese financing was always expected to play a central role. More recently, the total estimated cost has been brought down from around $9 billion to about $6.66 billion, and the Asian Development Bank has also entered the picture, holding detailed talks with Pakistan Railways officials over scope, design, and financing structure for parts of the upgrade — though formal ADB funding approval was still pending as of the latest reporting.
In practice, this means ML-1 is likely to be funded through a mix of sources rather than a single lender, which is fairly typical for a project of this scale spanning multiple phases and years.
ML-1 Project — Frequently Asked Questions
Click on a question to expand the answer
ML-1 stands for 'Main Line 1' — the 1,726-kilometre core railway corridor running from Karachi through Rohri, Multan, Lahore, and Rawalpindi up to Peshawar. It carries the vast majority of Pakistan's rail passenger and freight traffic, but much of its track, signaling, and bridges date back decades. The ML-1 project is a full modernization of this corridor: dualizing single track sections, replacing worn-out track, upgrading signaling, and rebuilding stations, so trains can run faster, more frequently, and more safely.
The project's estimated cost has been revised down from an earlier $9 billion figure to around $6.66 billion. It was originally conceived as a flagship China-Pakistan Economic Corridor (CPEC) project, and the Asian Development Bank (ADB) has also been in detailed discussions with Pakistan Railways over financing structure, scope, and design for parts of the corridor.
According to Pakistan's Minister of Railways, physical work was set to begin from Karachi Port in July 2026, with the first phase covering the roughly 480-kilometre Karachi-to-Rohri section. That first phase carries an estimated construction cost of around $2 billion and a targeted completion window of about three years from groundbreaking.
Not immediately. ML-1 is being rolled out in phases over several years, starting with Karachi-Rohri. Passengers on that specific stretch will see benefits first as sections are completed and reopened at higher speeds; other parts of the Karachi-to-Peshawar corridor will follow in later phases. Expect a gradual, multi-year rollout rather than a single switch-over date.
Both. In fact, freight capacity is one of the biggest drivers behind the project — a modernized ML-1 is expected to let Pakistan Railways move significantly more cargo per train and per day between Karachi's port and the rest of the country, which matters as much for the national economy as passenger comfort does.
