Tube ponderings with Barry Heck
Our resident tube fancier dishes out daily thoughts on the London Underground.
Head to the north-west corner of the Bank of England and you'll find this grille taking up a fair portion of the carriageway. A sign handily tells us what it is — the DLR overun tunnel. This is the western-most section of the DLR, and the bit in which trains change direction (minus passengers) just beyond Bank. My thanks to tube know-it-all Geoff Marshall for taking me to see this overlooked feature. Follow Barry on Twitter @HeckTube.
