This Talking Railroad Crossing has a built-in motion sensor that triggers the gate and activates cool railroad sounds, along with a warning "The train is crossing and stay clear of the tracks." In English, Spanish and French no less. When the gate goes up, zooming car sounds are heard, along with a message that it"s safe to cross. Big fun in teaching a valuable lesson to riders. 8"L x 22"W x 32"H. Minimal adult assembly required. Requires 3 "AA" batteries (included). Made of plastic (add water to base for more stability).
