The sliding door and plug door are the main types of door system in the Electric Multiple Unit (EMU). The sliding door is widely used in Korea but has weak in the noise problem. In the low operation speed, the noise coming from outer side of the EMU is not an important factor. As the speed is higher than before, noise is increased and make an issue. The main cause of noise is the imperfect air tightness in the EMU. The plug door system has advantages for the noise reduction characteristic in the high speed area. Actually the noise level is an important factor for the passenger comfort. In this paper, we will describe the characteristic of electric plug door and functions of sub component. Expecially we describe a function of preventing door locking release.
