Orange line will begin at Thailand Cultural Centre station and run eastward to Suwinthawong.

In 2020, cabinet approved the extension of Orange line from Thailand Cultural Centre westward to Bang Khun Non.

After initial investigations, it was found that the empty train had run into problems shortly before the accident, grinding to a halt on a curve leading to the depot.

The driver applied its brake and was waiting to be towed to the maintenance center close to Thailand Cultural Centre station.

The Metro resumed full operation on 1 February 2005, and passenger numbers soon rose back to pre-crash levels, partly due to a temporary promotional fare scheme which allowed passengers to travel any distance on the MRT for only ten baht (~0.33 USD).
