Trouble in the Tunnel is a Step Into Reading book released in the summer of 2010 published by Random House.
Thomas, Bash, and Dash are shunting flatbeds of Jobi Wood inside a tunnel. Suddenly the tunnel starts crumbling and they are trapped!

- Misty island tunnel is illustrated with a double track, but it's meant to be a single track.
