Here is an easy recipe for wooden railway fun: Set up this amazing
four-piece accessory (over 30" long when assembled), add track and trains,
and enjoy! Compatible with all popular wooden railway sets such as Brio,
Thomas, Chuggington and more, this bridge and tunnel with its removable
"waterfall" will increase the number of layout options for hours of train
excitement. Just quickly remove the waterfall scenery to convert to a
bridge/tunnel combination. Trains & track not included.
