6 . On a tram smoothly pulling into the heart of Luxembourg City, Marck gives a smile and takes a look at the fabric of the seat next to him. For him, the city’s trams are more than just transport. More even than the focus of his job. They are about transforming his country and, perhaps, changing the world.

Marck is the director general of Luxtram, Luxembourg’s modern trams. It first started running services two years ago. Next year, Luxembourg will become the world’s only country to get rid of fares on all its forms of public transport. Luxembourg’s traffic problems come from its army of workers. The population of the capital city almost doubles during the working day, when more than 110,000 people travel in and out.

After three decades when its roads have become so crowded, Luxembourg is going to do something remarkable. Free fares, and a plan to persuade people to switch from cars to trams or trains. Marck, along with many others, is excited to see what happens next. “The fact that this is free means that everyone can use it — young or old, rich or poor,” he said. “Everyone can say to themselves it’s better to leave the car at home. We must continue to improve and extend the network. It must always be comfortable, well-connected, efficient.”

Lydie Polfer, the city’s mayor, says she hopes to reach the point where more than a third of people come into the city using public transport — at the moment, it’s less than one in five. She said, “It’s not practical to ban cars because some people, like the elderly, need them. But everyone has to be aware that he or she can do something to improve the situation. There is an expression in German — you are not in the traffic jam — you are the traffic jam, and that is true. I think that making it free will be the biggest arguments for people to use public transport. ”

The Grand Canal of China was first dug in 486 BC, and well developed through the late 6th to early 10th century. From the late 13th until 19th century, with the highest section built and the overall length     1    (shorten), the Canal was turned into a main passage between northern     2     southern China as well as the economic lifeline of the country. Consisting of the Sui and Tang Grand Canal, the Jing-Hang Grand Canal and the Zhedong Canal, the Canal     3    (stretch) over 2, 700 kilometers, crossing eight provincial-level administrative regions and     4    (link) five major water systems.
