This is the tallest TrackMaster set ever made, bringing Train-play to new heights with a two-foot mountain. The play set comes with a complete loop of winding mountainous track, two working cranes, and the main feature is a breathtaking drop-bridge that drops the engine down onto the tracks just before he steams over the edge. The child can use the cranes to load and unload rocks at the quarry, and then use the switch track to send the engine around the mountain track or up to the drop-bridge.
