A new monorail/tram line connecting the city center, beach areas, and external hubs will create significant real estate investment opportunities.

Green Line: HSR Station → Pattaya City Center → Thappraya → Bali Hai Pier (13 stations).
Red Line: ~17.37 km, 10 stations. Route: Thap Phraya Intersection → Jomtien Second Road → Chaiyaphruek 2 Road → Eastern National Sports Training Centre.
