Before then, while in the case of the Series 8000 the letters were written in red on a black background, in the case of the Series 3000 the letters were written in red on a white background, and when the series was renovated in 1995 the rollsign became the same design as the Series 8000, with red letters on a black background.
それ以前は、8000系は黒地に赤文字の幕を、3000系は白地に赤文字の幕を使用しており、1995年の更新工事の際に8000系と同様の黒地に赤の幕となった。
