NORTH WOOLWICH LINE
Opened in 1846 between Stratford and Canning
Town, the line was extended to North Woolwich the following year.
Services were extended north to Palace Gates in 1887 although
that line (northwards from Seven Sisters) was closed to passengers
in 1963. All North London line services were withdrawn from the section south of Stratford in 2006. The DLR extension to Stratford International has taken over the line as far south as Canning Town. The Custom House to North Woolwich section will be used by Crossrail. |
Connaught Road tunnel (aka Albert Dock tunnel / Silvertown tunnel)
When the Victoria Dock was built, a swing bridge was put in at its entrance. However it was thought that the opening and closing of the bridge would interfere with the train services so a new route for the line was built to the north of the dock. The route of the line was interruped again when the adjacent Albert Dock was opened; a new cut & cover tunnel was built underneath its entrance. The tunnel has been extensively altered and repaired in preparation for its re-use by Crossrail. |

The tunnel layout is symmetrical. There are long buttressed sections at both tunnel approaches. (photo: 2009 by John Simmonds) © 2009 John Simmonds |

The initial double tracked width became two single track tunnels. Note the airshaft in the roof. (photo: 2009) |
||||
Taken from slightly further back five years later: the two single tunnels have been removed and replaced by one double track tunnel. The concrete sections at the bottom of the walls on either side show where the floor has been lowered - the original tunnel floor was at the top of the concrete sections. (photo: Sep 2014) |

Looking up at the airshaft. There is a matching one at the other end of the single bore tunnels. They are situated either side of Connaught Bridge. (photo: 2009 by John Simmonds) © 2009 John Simmonds |

The same airshaft five years later after the twin tunnels were removed and a new box section inserted when the dock above the tunnels was drained dry. (photo: Sep 2014) |

Surface view looking in a south-easterly direction. The north-western airshaft is in the foreground. The south-eastern one on the other side of the dock entrance is arrowed, showing that the route of the tunnel skews across the line of the bridge. The bridge - Connaught Bridge - is a replacement for the one that used to carry the line over the dock entrance (the first alignment of the line followed what is now Silvertown Way and North Woolwich Road. The building of the Royal Victoria Dock cut through the railway's route so a new alignment around the north of the dock was built. This lasted until the Royal Albert dock was built, again cutting through the line's route, at which point the Connaught Tunnel was built). (photo: 2009) |

The swing bridge remained in use by the dock company but was replaced by the Connaught Tunnel for passenger trains. (photo and copyright: Tom Burnham from his Flickr site. Used with permission.)
