The viaduct in the distance
By Rob Barlow
The building of Yarm viaduct in 1848 was a remarkable feat of engineering. There were no mechanical excavators or mobile cranes to call on at that time.
It had to be hauled into position by teams of horses and a pulley system. Yet the structure was completed in just over 4 years.
The viaduct has 43 arches, two of which carry the railway over the River Tees, these are 65ft high and have spans of 67 ft and took 139,000 cubic feet of stone to build.
The official opening was in May 1852.
On an exceptionally dark wet night, a train overshot the platform and an unsuspecting stranger to the area in alighting from his carriage, stepped over the parapet and fell 74 ft.
