I know … lots of pictures have been taken of Tower Bridge and plenty posted on the internet. But I couldn’t help it! Lovely Thursday evening, London, April 2017.
About the Tower Bridge
“When it was built, 122 years ago, the Tower Bridge was the largest and most sophisticated bascule bridge ever completed (“bascule” comes from the French for “see-saw”). These bascules were operated by hydraulics, using steam to power the enormous pumping engines.
The energy created was stored in six massive accumulators, as soon as power was required to lift the Bridge, it was always readily available. The accumulators fed the driving engines, which drove the bascules up and down. Despite the complexity of the system, the bascules only took about a minute to raise to their maximum angle of 86 degrees.
Today, the bascules are still operated by hydraulic power, but since 1976 they have been driven by oil and electricity rather than steam. The original pumping engines, accumulators and boilers are now exhibits within Tower Bridge Exhibition’s Engine Rooms.” Learn more
