3 most important railroad bridges over the Thames situated in London:
Cannon Street Railway Bridge
It is the railway bridge in central London, it links the districts of Southwark Bridge and London Bridge. It is designed for rail transport to Cannon Street Station, located on the northern side.
Originally the bridge was called Alexandra Bridge, in honor of the daughter of King Christian IX of Denmark, the Danish and the wife of King Edward VII. Bridge designers were John Hankshaw and John Wolfe-Barry.
Construction work lasted three years, and in 1866 there was an official opening of the bridge, which originally had five arches and was built with iron columns in the Doric style. Soon after opening in years1886 - 1893, the bridge was extended to Francis Brady and in the years 1979 - 1982 has been renovated and the elements of decorating were removed.

Blackfriars Railway Bridge
This railway bridge on the River Thames in London is situated between the road bridges: Blackfriars Bridge and Millennium Bridge. Blackfriars Railway Bridge is underpinned by massive columns, which will further sustain the pressure of passing on the high speed trains. This bridge was opened in 1864. Blackfriars Railway Bridge and Blackfriars Bridge make a single, but first one is the railway bridge and the second is a road for pedestrians. The designer of these two bridges was Joseph Cubitt.

Hungerford Bridge
It is the railway bridge over the Thames in London, situated between Waterloo Bridge and Westminster Bridge. The current bridge consists of a steel construction beam passing at the middle of railway tracks, this part of the bridge is known as Charing Cross Bridge, and on the left and right edge of the bridge there are located sidewalks intended for pedestrians called the Golden Jubilee Bridges. Originally the bridge was designed by British engineer Isambard Kingdom Brunel as a pedestrian bridge in 1845. In 1859 the bridge was purchased by the railway company to extend the South Eastern Railway to the newly built railway station Charing Cross. Then the rebuilding of the bridge was necessary for the movement of trains, the new bridge was designed by John Hawkshaw and was made of forged steel. In the 90s of the twentieth century they started to exchange sidewalks for pedestrians on the new more stable and durable, so this part of the bridge has gained a new name Hungerford Footbridges. There was also the lighting mounted on the bridge.

For comparison, one of the largest railway viaducts in Europe, located in Poland is a railway viaduct in Boleslawiec over River Bobr: 490 m in length.
