Here we go guys, an awesome explore down in the East End of London, no less!!, Connaught Tunnel was built in 1880, underneath the Royal Albert Dock to link the North London Line to the North Woolwich section of the Line. The tunnel is around 600 yards long and splits into two separate bores directly under the Dock. Enough waffle, the pics,... Sivertown Station and Tunnel approach Stonewalled Approach Cutting
