MRT Line-4 Project

MRT Line-4 Project Overview

MRT Line-4 is an east-west corridor within Dhaka's urban rail network, designed to connect the eastern and western sides of the capital. Dhaka Mass Transit Company Limited (DMTCL) is responsible for implementation, and the line is positioned as a core project for improving cross-city connectivity within the broader metro system.

Line-4 is expected to intersect with the existing north-south MRT Line-6 and create a wider transfer network across Dhaka. In particular, it would link fast-growing eastern districts such as Basantek and Baridhara with western urban areas, expanding mobility options for commuters and strengthening network integration.

Participation Strategy for Korean Companies

Civil Works for Elevated Sections

Because Line-4 is planned as a fully elevated corridor, Korean contractors can directly apply their experience in elevated metro construction. Korea Construction B's work on the elevated section of MRT Line-6 is a particularly relevant reference, while capabilities in MSS and FCM methods will likely remain important differentiators.

Rolling Stock and Systems Packages

Korean suppliers can propose integrated packages combining Korea Rotem rolling stock, CBTC signaling solutions from Korean rail system firms, and LTE-R communications systems. Existing experience supplying Korean rolling stock to Line-6 can be used to highlight parts compatibility and long-term maintenance efficiency.

Use of ADB and AIIB Financing Frameworks

Line-4 is expected to proceed under ADB and AIIB financing. Since ADB-funded projects are typically procured through international competitive bidding, success will depend on both technical quality and pricing. Korean companies may need to combine technology leadership with financing support such as KEXIM-backed project financing.

Station Architecture and Design

There is also room for Korean participation in station architecture, design, and construction. Experience from Seoul's metro system in universal design, transfer circulation optimization, and commercial space integration can be positioned as practical strengths for Dhaka's future stations.

MRT Line-4 is likely to become a key east-west artery in the Dhaka metro network. For Korean companies that have already established references through Line-6, it presents a practical pathway to pursue follow-on contracts in Bangladesh's expanding urban rail market.
