The city's first subway line extended from the Hong Kong border at Luohu westwards. Today, it is still a congested line stretching along the length of the city.
Futian is now an underground high-speed train station linking Guangzhou and, in the future, Hong Kong.
In Korea, gas masks are stored at each subway station in anticipation of a North Korean attack. In Shenzhen, this station has fire-fighting equipment ready for use.

Fares are relatively cheap by international standards. 2 yuan is about 30 cents US.
Many subway lines are under construction, just like other large Chinese cities. Hopefully, car culture won't engrain itself here like in North America.
Even after new lines are built, some of the infrastructure is under-used. These exits are barricaded off.
Lines that run above ground offer great views of the sprawling city.
The Longhua Line is the first operated by Hong Kong's MTR Corporation. Even the announcements are from the familiar Hong Kong voice.
Shenzhen North is a massive station serving the fastest trains to Guangzhou South.
The Shekou Line stretches into the further areas of Nanshan. The trains are not as crowded and looked a bit newer.
The 51km-long Line 11 opened in June 2016 with a distinction that there is a special Business Class section. Running express within the city, the journey from the airport to Futian takes only 30 minutes with a standard fare of 7 yuan or a premium fare of 21 yuan.
Both single and double-decker buses ply the city's streets.
