A specially designed theme train "HAPPY TRAIN" features welcoming pictures of Sam and Winson on the door and an interior design featuring blue skies, white clouds, a smiling clock, and a lovely bubble bath background. The "HAPPY TRAIN" will run on the Tsuen Wan Line from today to the end of August to offer passengers a comfortable, cheerful and relaxing atmosphere. Moreover, "MTR InfoPanels" inside train compartments from time to time show jokes to refresh our passengers.
