近年来，城市轨道交通发展迅速，为居民绿色出行提供了便利。重庆轨道交通更是穿山越岭、跨越两江，穿梭在街巷和楼宇间，成为独具特色的风景线。

Look!A light rail train is passing through a residential building in Chongqing.How amazingit is!

"Our city has very limited space.That can make finding room for roads and rail transit lines difficult,"a transport official from Chongqing says.Chongqing is in southwest China.It is known as the"Mountain City".Chongqing has a large population of more than 32 million people.So the sity's planners have to think up new ways to save space.

Chongqing Rail Transit Line 2 is a good example.The rail thransit line was built across a residentail building.It is a new way to make space for important rail thansit lines. Liziba Station is on the sixth to eighth floor of the building.It's good for the residents in the building to catch the train.The train is also famous for being very quiet. It is only as loud as a dishwasher when it moves.

看！一列轻轨列车正在穿过重庆的一幢住宅楼。真是太神奇了！

一位重庆交通官员说：“我们的城市空间非常有限。那可能会使为道路或轨道交通线路寻找空间变得困难。” 重庆位于中国西南部。它因“山城”著称。重庆人口众多，有3200多万人。因此，城市规划者必须想出新的办法节省空间。

重庆轨道交通2号线就是一个很好的例子。这条轨道交通线路横跨一幢住宅楼。这是为重要的轨道交通线路腾出空间的一种新方法。李子坝站位于大楼的第6至8层。这对大楼里的邻居赶列车有好处。这列列车也已非常安静而闻名。当它行驶时，声音只有洗碗机的声音那么大。
