Bust-Through Mine Tunnel is an Add-on destination for Trackmaster playsets where the incumbent blue engine's task is to be flung out of a tunnel with the help of a switch outside.
The description reads; Thomas is stuck in the mine tunnel. Push down on the T-handle so Thomas can break through the barricade!
Very little is included in the sizeable product with just the tunnel and a model of Thomas, part of the mix.
Bust-Through Mine Tunnel from TrackMaster arrives in stores worldwide later this year.
Thanks to SteamTeam for the alert.
