Plarail, a 3-car train of JR vehicles. - Model: JR Vehicle - Color: Gray/Green - Type: Plarail Vehicle - Configuration: 3-car train I am selling my E231 series, Yamanote Line, to organize my collection. This vehicle is being sold at a low price because it is considered junk. The wheels of the lead car are yellow. The wheels of the middle and rear cars are gray. Please refrain from purchasing if you are concerned about this. Thank you for viewing.
