One of London's famous tourist attractions is being modernised. As a result, three rather unusual engines are being offered for sale.
The 20-ton hydraulic engines are among four installed at each end of the bridge to raise the two huge 1,100 ton (tonne) bascules over which road traffic passes.
The engines were installed when the bridge was opened in 1894 since then have raised the bascules more than half a million times without faltering. They still work as well as they did when installed but are being replaced by more economical electrical equipment.
The other five hydraulic monsters will remain in place and, with two steam pumping engines, will form a museum.
