Tube is the nickname for the London Underground only. Glasgow's underground railway is called a subway* and the one in Newcastle-upon-Tyne is called a metro. Although some might refer to the rolling stock in Tyneside as trams which I believe are called streetcars across the Atlantic. Usually in the UK subway means a pedestrian underpass. You still with me?CAN: Subway/Metro
US: Subway
UK:Tube
* Allegedly the nickname for the Glasgow subway is the Clockwork Orange (that being the official colour of the regional transport authority) but I suspect that may be one of those nuggets of misleading advice invented to fool tourists.
The best example I know of is this sentence which has completely different meanings in British and American English:
I was mad about my flat
I was crazy about my apartment (GB)
I was angry about my flat tyre (US)
