Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 23 p. 24. Works numbers were 17739-17740 in May 1900.
The Tientsin-Pukow (which lay across the river from Nanking) was first bruited by German interests in 1899. After fits and starts and a couple of wars, the German concession was revived in 1908. At this point the Chinese government was able to insist on relatively favorable terms. The 674-mile line did not open to through traffic until 1912 and consisted of the German-built Northern section and the British-built Southern portion.
