Brian Baker looks at the rapid growth of Guangzhou's transit system:
"The initial 5.4km section of Line 1 opened in 1997 and linked Xilang with Hangshwa along an east–west corridor. In 1999 it was extended to Guangzhou East rail station and traversed 18km with 16 stations."
"By November 2010 the Guangzhou metro network totalled 236km with 144 stations. There are 8 lines. And not all of them are limited to the city and environs. The network had expanded by 170km in five years. The metro system now reaches into the outer suburbs of the city and beyond the city boundaries."
