How long is the mail in london

The Mail Rail, also known as the London Post Office Railway, was a underground railway system that was used to transport mail between sorting offices in London. It was operational from 1927 to 2003.

The Mail Rail was approximately 6.5 miles (10.5 kilometers) long and had 21 stations. It was a narrow-gauge railway, with tracks that were only 18 inches (457 millimeters) wide. The trains were designed to carry mailbags and were powered by electric motors.

The Mail Rail was an important part of London's postal system, allowing mail to be quickly and efficiently transported between sorting offices. However, with the decline of traditional mail and the rise of electronic communication, the railway was eventually closed in 2003.

Today, some sections of the Mail Rail have been converted into a museum and tourist attraction, known as the Postal Museum. Visitors can take a guided tour of the tunnels and learn about the history of the Mail Rail and its significance in London's postal system.
