LEGO DUPLO 10425 Tunnel and railroad track expansion pack.

This creative buildable toy contains a tunnel and 10 tracks, including a funnel element and a switch so kids can change the train's direction of motion. The multifunction brick lights up the dark tunnel when activated by the interactive train in sets 10427 and 10428.
