How long was the mail railway in central london

The Mail Rail, also known as the Post Office Railway, was a narrow-gauge railway that operated in Central London from 1927 to 2003. The railway was approximately 6.5 miles (10.5 km) long and ran from Paddington Station in the west to Whitechapel Station in the east, passing through the heart of London.

The railway was built to transport mail between the main post offices and sorting facilities in London, and it played a crucial role in the UK's postal system for over 75 years. The railway had 21 stations and was operated by the General Post Office (GPO).

The Mail Rail was closed in 2003 due to declining mail volumes and the increasing use of road transport for mail delivery. The railway's infrastructure was subsequently sold to a property development company, and the tracks were lifted in 2013 to make way for a new office development.

Although the Mail Rail is no longer in operation, it has left a lasting legacy in London's history and has been the subject of several books, documentaries, and exhibitions.
