Forty parents and students joined the MTR Little Regulator activity on 15th December, 2018. They visited the workplace of the MTR regulators, learned about the daily operation of the MTR trains, and even entered the control room of the MTR trains. It was such an eye-opening experience. The students dressed up as MTR Little Regulators and distributed "safety" stickers to the passengers at the MTR Tai Wo station lobby. They also used the "stop" signs. Everyone was so enthusiastic!
