Nokia, ST Engineering to build Bangkok Orange Line rail network by 2030

Nokia, in partnership with Singapore’s ST Engineering and Thai ICT firm First One Systems, has been contracted to deploy an IP/MPLS-based Backbone Transmission Network (BTN) for Bangkok’s upcoming Orange Line metro, which is expected to be completed by 2030. This 35.9-kilometer urban rail line will connect the eastern and western parts of Bangkok, featuring both underground and elevated sections. Nokia’s solution includes high-capacity 10G and 40G networks using equipment such as the Nokia 7250 Interconnect Router and 7210 Service Access System, designed to support critical railway applications including CCTV, passenger information systems, public announcements, radio communications, and supervisory control. The network aims to provide a secure, low-latency, and reliable communication backbone to enhance operational efficiency, safety, and real-time performance monitoring for the Bangkok Expressway and Metro Public Company Limited (BEM). Project partners emphasize their combined expertise and local knowledge to deliver a world-class, mission-critical communication system meeting international standards. The initiative reflects a wider trend in digital transformation of railway systems worldwide to improve safety and service reliability.
