Stationary steam engines are fixed steam engines used for pumping or driving mills and factories, and for power generation. They are distinct from locomotive engines used on railways, traction engines for heavy steam haulage on roads, steam cars (and other motor vehicles), agricultural engines used for ploughing or threshing, marine engines, and the steam turbines used as the mechanism of power generation for most nuclear power plants.

The development of the steam engine was gradual. They were introduced during the 18th century and widely made for the whole of the 19th century and most of the first half of the 20th century, only declining as electricity supply and the internal combustion engine became more widespread. Over time, they would improve in pressure, expansion and speed.

St Katharine Docks is a former dock in the St. Katharine's and Wapping ward of the London Borough of Tower Hamlets. It lies in the East End on the north bank of the River Thames, immediately downstream of the Tower of London and Tower Bridge. From 1828 to 1968, it was one of the commercial docks that made up the Port of London. It is in the redevelopment zone known as the London Docklands and is now a housing and leisure complex.

A bridge tower (German: Brückenturm) was a type of fortified tower built on a bridge. They were typically built in the period up to early modern times as part of a city or town wall or castle. There is usually a tower at both ends of the bridge. During the 19th century, a number of bridge towers were built in the Gothic Revival style – Tower Bridge in London is perhaps the best known example; however, many original medieval towers survive across Europe.

The London Inner Ring Road, or Ring Road as signposted, is a 12-mile (19 km) route with an average diameter of 2.75–5.5 miles (4.43–8.85 km), formed from a number of major roads that encircle Central London. The ring road forms the boundary of the London congestion charge zone, although the ring road itself is not part of the zone.

Starting at the northernmost point and moving clockwise, the roads defining the boundary are Pentonville Road, City Road, Old Street, Great Eastern Street, Commercial Street, Mansell Street, Tower Bridge, Tower Bridge Road, New Kent Road, the Elephant & Castle, Kennington Lane, the roads that constitute the Vauxhall Cross one-way system and Vauxhall Bridge, Vauxhall Bridge Road, the roads that constitute the Victoria one-way system, Grosvenor Place, Park Lane, Edgware Road, Old Marylebone Road, Marylebone Road and Euston Road.

Tower Gateway is a Docklands Light Railway (DLR) station in the City of London and is located near the Tower of London and Tower Bridge. It adjoins the tracks to Fenchurch Street station and is located on the site of a former station called Minories. Tower Gateway is within London fare zone 1.

It is a short walk from both Tower Hill Underground station and Fenchurch Street. Access at street level from the Minories is via escalator, stairs or lift at the western end of the station. A pedestrian crossing connects the station with Tower Hill station, its closest London Underground connection. A narrow secondary staircase entrance at the eastern end of the platform, improved considerably in the early 2000s, descends to Mansell Street. It serves the eastern edge of the City of London central business district and development around St Katharine Docks.
