PATTAYA, October 2025 — As Thailand continues to expand its urban transportation networks, the proposed Green Line monorail project in Pattaya marks a significant step in the region’s infrastructure development.

The Environmental Impact Assessment (EIA) for the approximately 9.9 km Green Line, which is planned to run from the future high-speed rail station in Pattaya through the city centre to Bali Hai Pier, is currently being finalised and expected to be submitted shortly for review. The project is intended to be delivered under a public-private partnership (PPP) model.

Once the EIA is completed and submitted, the next steps include a feasibility study by the National Economic and Social Development Council (NESDC), followed by Cabinet approval of the investment model. If these approvals proceed smoothly, the project will advance to the procurement and construction stage.

The Green Line is envisioned as the pilot route of a wider four-line monorail network in Pattaya, which also includes the Yellow, Purple, and Red Lines. The Purple Line, stretching about 11.4 km, is expected to enter the next phase of planning, with construction anticipated to begin in 2027.

By enhancing connectivity within Pattaya especially between the planned high-speed rail hub, the city centre, and coastal destinations like Bali Hai Pier the project aims to support both tourist mobility and local economic activity. It also aligns with Thailand’s broader goals of modernising public transport infrastructure and improving regional intercity links.

While major design, approval, and investment decisions are still underway, the Pattaya monorail initiative reflects the city’s aspiration to become a more connected, sustainable, and tourism-friendly urban centre.
