Tube ponderings with Barry Heck
Our resident tube fancier dishes out daily thoughts on the London Underground.
Time, once again, to play my special patented game. It's called 'Name that tube station based on a cryptically oriented screengrab from Google's Street View'. (I need to work on the title.) Today's puzzle is taken from the exit to a well-known station. But where? The first person to tweet the correct answer to @HeckTube wins an empty tube of toothpaste that I've been pondering how to recycle.
Good cause of the day
Govia Thameslink Railway has partnered with several homeless charities to launch the Great Sock Appeal. Tomorrow (5 December), a donation point will be set up at Blackfriars railway station for one day only, where members of the public can donate a new pair of socks for those who need them as the cold winter weather arrives.
