Henry's Tunnel is a tunnel on the North Western Railway.
The tunnel features three lines of track going through it. Shrubbery is seen on and around the tunnel, and it is situated between two hills in a small valley.
In Henry refused to come out of the tunnel because he was afraid that the rain would ruin his paint. The tunnel was then named Henry's Tunnel because of this.
A battle between Cody's army and Professor's Gang took place on the hill next to the tunnel. At one point, Cody fell onto the rails in front of the tunnel and Stan and Kate drove a truck off of the hill, crashing in front of the tunnel.
- The tunnel is made from a shoebox with foam in the middle to seperate the two sections.
