Sangū Line
After the war, the Sangū Line saw its first rival train line which was owned by Kintetsu who offered express service from Osaka and Nagoya. However, the Sangū Line maintained its competitive edge in the 1940s and 1950s because Kintetsu was, at the time, not yet able to offer direct service from Nagoya due to differences in track gauge, so passengers that were coming to Ise Grand Shrine via Nagoya were forced to change trains during the journey if they took Kintetsu, thus many people opted to take the government-owned Kokutetsu option instead since it was direct.
