【AUTO-SWITCH, TWO-TRAIN ACTION】The switch track aligns when needed, helping two USB-C rechargeable, light-up electric trains follow different routes and merge smoothly onto the main train track. 【3-LEVEL ELEVATOR ADVENTURE】 This 106-piece electric train set for kids lets children choose the exit floor before each ride, then watch as the train powers the lift—adding height, surprise, and new ways to play to every run. Each train runs for approximately 45–60 minutes per charge.
