JGR Class 7170
 The Japanese Class 7170 steam locomotive was among the first trains to be used in Hokkaido and was utilized alongside the JNR Class 7100 on the Horonai Railway. The two tender locomotives that were to become the Class 7170 were purchased from the American Baldwin Locomotive Works in 1889 and were included into the numbering sequence of the six 7100 trains as numbers 7 and 8.
