Tube ponderings with Barry Heck
Our resident tube fancier dishes out daily thoughts on the London Underground.
The Piccadilly line continues to throw up some unusual station information. I snapped this a few days back, suggesting a destination of T2throw, stopping at terminals 1, 2, 3 and 5. All a bit worrying, considering terminal 1 closed four years ago. If you've spotted other weird destinations on the Piccadilly, feel free to share by tweeting them to @HeckTube.
Good cause of the day
