The Metropolitan Rapid Transit, or MRT, is a rapid transit system serving the Bangkok Metropolitan Area in Thailand.
The Sam Yan Station is right next to the university. Just leave through Exit 2 below Chamchuri Square, which is one of the university buildings where you can begin your visit. From here, you can walk, board a bus or hire a taxi to go to a specific building or faculty on the university campus.
