Do you like travelling by train?The people in Belgium do.In 1991,the National Belgian Railway Company built the longest train in the world.It weighs 2,786 tonnes and is 1,733m long ---that's nearly 2km long!Ifthis train came to Hong Kong,the front would arrive at Sha Tin KCR station while the back was still in Tai Wai!
