The Brio 1/4 expansion track mix set offers a practical extension for your wooden railway. It contains four short wooden track pieces that make it easy to close gaps in the track layout. The expansion tracks fit standard wooden railway tracks and allow for flexible track building. Two track pieces feature male connectors on both sides, while the other two track pieces are equipped with female connectors on both sides. This allows them to serve as connectors to balance out changes in connection directions. The precise craftsmanship ensures a smooth transition when driven over by your toy trains.
