The Chosen Government Railway's public identity changed a number of times over the 39 years that it existed.

Today's Daejeon Korail FC is the direct descendant of Sentetsu's football club, which won the All-Korea football championship in 1939;[2] Sentetsu's ice hockey club was the first to ever play a game of that sport in Korea, playing a game against the team of the Tokyo Imperial University in 1928, and later played the first game between two Korean clubs, against a team from the Gyeongseong Imperial University.

Mantetsu management lasted just under a decade, and by the time Sentetsu regained its independence in 1925 the locomotive park stood at 247 engines.

This slightly modified in 1918, the year after Mantetsu took over management of Korea's railways, with some of the numbers being redefined, and after Mantetsu introduced a new classification system for its own locomotives in 1920, the system for Korean locomotives was once again adjusted, retaining the number series as they were in 1918, but adding new class designations - likewise reflecting wheel arrangement - akin to those used for Mantetsu's own locomotives, based on the common American name for the given wheel arrangement.

[5] The first two, indicating wheel arrangement, remained as they were in the previous system, with the addition of one: マテ (Mate), from "Mountain", for 4-8-2 locomotives introduced in 1939.

Narrow-gauge steam locomotives did not use the designation forms based on wheel arrangement; instead, they all used ナキ ("Naki", from English "Narrow Gauge") plus a class number.

In practice, Sentetsu had only two types of electric locomotive, both with six powered axles - デロイ (DeRoI) and デロニ (DeRoNi).
