SINGAPORE - Transport Minister Khaw Boon Wan visited 19-year-old train enthusiast Isaac Nathaniel D'Souza earlier this week.

Mr Khaw said in a Facebook post on Thursday (May 18) that he visited Mr D'Souza's "train city" which the young SMRT train service ambassador had built in his room.

Mr D'Souza, who lives in Sembawang, showed the Sembawang GRC MP his "huge collection of trains, complete with railway networks and nine running train tracks".

Mr Khaw said it took only two years for Mr D'Souza to build his miniature SMRT-themed city filled with electric train models, train tracks and train-related memorabilia, but it takes about 14 years to launch a train for passenger service.

In a video attached to his Facebook post, Mr Khaw is shown sitting with Mr D'Souza in the middle of the train system, watching how the controls work. He also takes a 360 degree photo with the teenager, showing the train-themed room, which was inspired by Mr D'Souza's workplace at Jurong East Station.

Mr D'Souza, who has been interested in trains since he was three, was featured in a video on SMRT's Facebook page on May 9.

He said he joined the company after working in several jobs in the hotel and food and beverage industries, when he realised it is "good to work in an industry where you are doing something you love".
