World History

Tuesday, August 2, 1870. :   Tower Subway, the first tube railway in the world, is opened under the Thames River in London.

     The London Underground is a public electric railway system that runs underground in central London and emerges above ground in the city's suburbs. It was the world's first underground network. Prior to its construction, London trains terminated a long way from the central city, as building them closer would necessitate damaging historic buildings. Buses were still required to bring commuters into the city, and London soon became gridlocked. In 1854, a short underground railway was implemented between Paddington and Farringdon, but was constructed using a simple cut-and-cover method of digging a trench and recovering it with a roof, using supporting beams.

Shortly after this, deep-level tunnels, or "tube lines" were developed. They ran about 20 metres below the surface, and the tunnels were reinforced with cast-iron rings. On 2 August 1870, the Tower Subway became the first tube railway to be opened, and it ran beneath the River Thames in central London, close to the Tower of London, entering at Tower Hill and exiting at Vine Lane. It was designed and built by James Henry Greathead in 1869-1870 using a cylindrical wrought-iron tunnelling shield he designed with Peter W. Barlow. Initially, a steam engine powered a 12-seat carriage shuttled from end to end by wire rope, in a 70 second journey. However, it was not popular or cost-effective and was closed down after three months.

Thought For Today
Do not let evil defeat you; instead, conquer evil with good.
Romans 12:21 (c) GNB
Don't let the actions of another determine your reaction. Always do what is right in the sight of God. Remember that two wrongs don't make a right.
