The JGR Class 4100 was a 0-10-0T high-pressure side tank steam locomotive built for the JGR from 1912 to 1913.

History

The 4100s were used mainly as freight locomotives and was able to cope with very steep gradients coupled with practically unheard of strength with regards to pulling power. Four locomotives were built in 1912 by J.A. Maffei of Germany and brought over to Japan via ship. The locomotives were retired in 1935.

No examples have survived into preservation, although it appears as though parts were cannibalized from locomotives 4100 and 4103 to produce a Class 4110 derivative, the Class E43. This theory has neither been proven or disproven.
