Sentetsu Goroi-class locomotive

The Goroi class (ゴロイ) was a class of steam tank locomotives of the Chosen Government Railway (Sentetsu) with 2-4-2 wheel arrangement. The "Goro" name came from the American naming system for steam locomotives, under which locomotives with 2-4-2 wheel arrangement were called "Columbia".

Description
Three Goro-class locomotives were built in 1923 by Kisha Seizō of Japan for Sentetsu, delivered in 1924. Initially numbered 61-63, they received the ゴロイ1 through ゴロイ3 numbers in Sentetsu's general renumbering of 1938.

After the partition of Korea, all three Goroi-class locomotives went to the Korean State Railway in North Korea, where they were designated 고로하 (Koroha) class and numbered 고로하1 through 고로하3.
