Pupils from Pei Chun Public School (above) being taught about train station operations during a training session at Toa Payoh MRT station last month. The SMRT's Adopt-a-Station initiative, which began in September 2014 and currently has 21 schools taking part in it, trains students to be service ambassadors and lets them serve the community near their schools while they learn how to be gracious commuters themselves.
