Photo taken on Feb. 21, 2017 shows some animal paws prints at an animal passage of the Standard Gauge Railway (SGR) near Voi, Kenya. Kenya's Tsavo National Park is the oldest and largest wildlife sanctuary in the African country. In the park, the China-funded Standard Gauge Railway snakes throughout an estimated 133-km stretch of plains. Thanks to engineering prowess and environmental consciousness from China Road and Bridge Corporation (CRBC), the SGR's contractor, the modern railway line has not diluted the pristine allure of the Tsavo National Park, contrary to fears voiced by some skeptics.
