The Guangzhou-Shenzhen-Hong Kong Express Rail Link will inevitably affect the business of other cross-border transportation providers.

MTR Corporation chief executive officer Chow Chung-kong said yesterday that 37 percent of commuters using the express link will be new travelers, and the remaining 63 percent will be users of other transportation services, including the existing through trains to Guangzhou East and cross-border coaches.

He added that the MTR Corporation may review the service frequencies of the through trains to Guangzhou East after the express link starts to operate.

But he added that the community will still have demand for the existing through train services because the terminus is located in the center of Guangzhou.

Hong Kong Guangdong Boundary Crossing Bus Association secretary general Chow Hing-wong expected that their business will be affected by the express link.

Currently, about 60 percent of commuters using the association's services are business travelers.

Chow estimated that about 30 percent of these business travelers will switch to the express link.

"Our operating conditions will certainly be affected," Chow said.
