There were many railways built in the UK that were later closed as uneconomical (rightly or wrongly). One line in particular is famed (sort of) for having only been used once before closure. Which company built it, and where did it run?

The Tower Subway, Baloo? Although not strictly part of the Underground System, the Tower Subway was the world's first underground tube railway. Constructed using the revolutionary Greathead Shield invented by James Henry Greathead (used subsequently for many of the other tubes), the train (actually a single carriage) was cable operated and was effectively used as a shuttle service between the two banks of the Thames. The railway unfortunately was only open from August 2nd 1870 until November the same year due to very poor patronage. The tunnels were resurrected as foot tunnels but even this was short lived as they were again made redundant by the building of the nearby Tower Bridge in 1894 and were permanently closed to the public and the tunnels were equipped with pipes to provide hydraulic power. http://underground-history.co.uk/front.php Feb 16 09, 2:16 PM

Nope. The one I'm looking for was only used once (OK, there and back once). Possibly a world record, definitely a UK record for short life. Feb 16 09, 2:31 PM
