In 1863 the first underground passenger railway in the world opened in London. It ran for just under seven kilometers and allowed people to avoid terrible {#blank#}1{#/blank#} (crowd) on the roads above as they travelled to and {#blank#}2{#/blank#} work. It took three years to complete and was built using an interesting method. This included digging up the road, {#blank#}3{#/blank#}(lay) the track and then building a strong roof over{#blank#}4{#/blank#} top. When all those had been done, the road surface was replaced.
Steam engines {#blank#}5{#/blank#}(use) to pull the carriages and it must have been{#blank#}6{#/blank#}(fair) unpleasant for the passsengers, with all the smoke and noise. However, the railway quickly proved to be a great success and within six months, more than 25,000 people were using{#blank#}7{#/blank#}every day.
Later, engineers {#blank#}8{#/blank#}(manage) to construct railways in a system of deep tunnels (隧道), which became known as the Tube. This development was only possible with the {#blank#}9{#/blank#}(introduce) of electric-powered engines and lifts. The central London Railway was one of the most {#blank#}10{#/blank#}(success) of these new lines, and was opened in 1900. It had white-painted tunnels and bright red carriages, and proved extremely popular with the public.
