Scotland is a country that is part of the United Kingdom.
"Scotland" comes from Scoti, the Latin name for the Gaels. The Late Latin word Scotia ("land of the Gaels") was initially used to refer to Ireland. By the 11th century at the latest, Scotia was being used to refer to (Gaelic-speaking) Scotland north of the river Forth, alongside Albania or Albany, both derived from the Gaelic Alba. The use of the words Scots and Scotland to encompass all of what is now Scotland became common in the Late Middle Ages.
Within the large cities, roads become congested in peak hours. The M8 and M77 motorways become heavily congested in peak hours, especially around Glasgow where it travels through the heart of the city. The main congestion hotposts are in Glasgow City Centre around the Kingston Bridge where a large amount of traffic leaves and enter the road. Also further down the road traffic joining at Hillington Estate and Braehead Shopping Centre near Glasgow Airport can cause hold-ups. Traffic is also extremely heavy between Glasgow and Edinburgh at all times, however rarely comes to a standstill.
Scotland has an extensive railway network using cross country links across the country, and connections to England; local commuter links to the major cities many were electrified under British Rail; and freight. Only 29% of the rail network in Scotland (by routes miles) is electrified, as opposed to 40% across Great Britain as a whole. This results in many trains being run on diesel fuel rather than by overhead electricity.
