容闳
Assisted by the young American-educated student engineer (a Yung Wing mission student), Kwang King Yang (Kuang Jingyang 鄺景揚 s: 邝景扬 ) also known as K.Y. Kwong and Kuang Sunmou, Kinder supervised the building of the extension which was completed in April 1887. Imported German Krupp rails were used, as well as a ten-wheeled 2-6-2 saddle-tank locomotive from the Grant Locomotive Works of New Jersey (No.4), and forty 10-ton coal wagons.
