In view of Tuesday's massive train breakdown, and given the train operator's breakdown record, it is high time chief executives and other senior management of train operators be made accountable for train service performance, and not just profit ("2 major MRT lines down for over 2 hours"; Wednesday).

Although SMRT is a private company, it still has a public service role to fulfil; SMRT should also be made answerable to the public and not just shareholders.

A significant portion of senior management's pay, and not just bonus, should be directly linked to breakdown in service performance and public satisfaction. In a bad service performance year, they should see a real wage cut, rather than just a reduced bonus.

We cannot have CEOs collecting millions of dollars in bonuses when the service track record is bad.
