A posed photograph demonstrating the method of hauling the segments through the subway to the shield on a bogie using a rope and block. Why? They were heavy - each segment weighed approx. 6 hundredweight or cwt. (112 lbs = 1 cwt and 20 cwt =1 imperial ton) i.e. 300 Kg. [009] [060]
If the images look a little washed out it is because I lightened both images to provide more of the detail which is lost in the darkened environment of the shield!
