Railway 'has not' affected antelopes' migration

The rare Tibetan antelopes, or chiru, that live on the Qinghai-Tibet plateau have adapted well to the high-speed trains that occasionally fly by above them, a zoologist has said.

"The heavy use of the underpasses shows the animals' migration habits have not been disturbed by the railway," Yang Qisen, who has been responsible for monitoring the railway's impact on wildlife since it opened five years ago, told China Daily.

A report produced by Yang and his team was published last month in the science journal Nature.
