Tube ponderings with Barry Heck
Our resident tube fancier dishes out daily thoughts on the London Underground.
You'd be forgiven for thinking that the central section of the Elizabeth line was about to open, given how prominent the signs are becoming. This massive glowing roundel is now on show outside the new Long Lane entrance to Farringdon station, while the signage below is from Moorgate. The line, also known as Crossrail, was due to open in December 2018. The current estimated opening date is 'as soon as practicably possible in 2021' — which could be two years away.

Good cause of the day
