It seems that the post you provided does not mention anything related to maintenance report feedback for a public flat house in Singapore. The post simply says "bye people moving purple train singapore" and does not provide any context or information that would suggest otherwise. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house.
