So much seems to be said in the one site that we just love:
The Man in Seat Sixty One - http://www.seat61.com/. It's all about going by train (or boat), anywhere around the world.
As it says on the front page : 'Maybe
you don't like flying, or are concerned about the environmental impact of
flying. Or perhaps you just prefer real travel by train or ship,
where the journey is part of the adventure... Either way, this website
will tell you how to travel overland comfortably & affordably where you
might think that air was now the only option.'
The site includes
information about traveling within Britain, with links to
National Enquiries : http://www.nationalrail.co.uk
GNER that runs north east of Britain: http://www.gner.co.uk
Chiltern Railways that runs between London and Birmingham: http://www.chilternrailways.co.uk
Virgin Trains, who run between the far north and far west : http://www.virgintrains.co.uk/
It also looks at
travelling overseas, across the continent and beyond.
