Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago.

Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move
- reduce eye strain

Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

SUMMARY
=======
Railway electrification in Great Britain began during the late 19th century. A range of voltages has been used, employing both overhead lines and conductor rails; the two most common systems are 25 kV AC using overhead lines and the 750 V DC third rail system used in southeast England and on Merseyrail. In 2006, 40%—3,062 miles (4,928 km) of the British rail network was electrified, and 60% of all rail journeys were by electric traction (both by locomotives and multiple units).According to Network Rail, 64% of the electrified network uses the 25 kV AC overhead system, and 36% uses the 660/750 V DC third-rail system.The electrified network is set to expand over coming years, as 25 kV electrification is extended to currently unelectrified lines, such as the Great Western Main Line, the Midland Main Line and lines in the North of England as part of the Northern Hub.
