Progress Rail has entered into a contract with the Ch. Thawee–AS Construction Joint Venture (CH-AS JV) to supply signalling and telecommunications systems for the second phase of Thailand’s double-track railway programme, focusing on the Khon Kaen–Nong Khai corridor.
The 167-kilometre scheme, which includes 11 stations, will introduce a second track and upgrade existing rail assets. The work forms part of Thailand’s national development plan, which aims to strengthen intercity rail links, lower logistics costs, and improve energy use across the transport network.

Under the agreement, Progress Rail will design, supply, install, test and commission a range of signalling and telecoms technologies. These will include a Traffic Management System, Computer-Based Interlocking, and European Train Control System (ETCS) Level 1 for both trackside and onboard deployment.
Hyung Kim, executive vice president of infrastructure for Progress Rail said:This marks our team's first wayside project in Thailand, building on our ongoing ETCS Level 1 onboard initiatives. To ensure optimal project execution and customer proximity, we are enhancing our presence in Bangkok with dedicated resources focused on managing and delivering the work.
The initiative is aligned with the State Railway of Thailand’s wider programme to modernise and extend the country’s rail infrastructure. CH-AS JV is acting as the principal contractor for the works.
