I believe I was the last to ask this question on here and without a reliable answer so this is great to see. Great Blog  . |

Great, thanks. It must have been quite eerie for the divers inspecting the damage!

Very interesting, thanks for posting this. The first 100m or so from the s/b Northern Line remains open & accessible, though can only be accessed from the running tunnel. There's a steel flood door leading into the loop tunnel. The tunnel continues for about 100 metres to a brick wall, with some spectacular stalagtites present as one nears the River. As far as I can tell, there is no evidence of where the loop was cut through by the 'new' southbound tunnel to Waterloo. On the northbound line, the last couple of rings on the immediate approach to Embankment can be seen to be a different profile, denoting the transition from the 1920s tunnel to the former loop tunnel. (I should add that public visits to the remaining section of Loop tunnel are out of the question as the tunnel can only be accessed from trackside). |

Fantastic stuff, first time I've even heard about its existence. Particularly liked the diagrams (as you can imagine  ) |

I contacted the press office to ask if access to the bulkhead area would be possible to take some illustrative photos for the article but got silence. Photos of that bit would have been a fantastic bit of atmosphere to add to the story - especially the stalactites! |

Not the easiest section of tunnel to access, as involves climbing over a cable run and then through the flood door which is only about 3ft tall! I took some photos inside the Loop tunnel a few months back. |

I second that, I'd love to see the loop photos!

I second that, I'd love to see the loop photos! I'll third it! The remnants of the loop are perhaps the only part of the entire Embankment complex that I never got to explore. I worked out of an 'office' on the District line EB in 1979-82 and spent many hours running cables all over the site and upgrading various comms assets and in later years got to work in all those areas that I had missed first time around except for the old loop which I had always thought inaccessible. When I get round to it I'll put some pics on Flickr. Beyond the brick wall there's no obvious means of access. I wonder if the under-river section may be accessible from the surface or at District Line track level, via the shaft marked on the plans? |

The brick wall you walked up to is likely to be the northern side bulkhead built after the bomb impact - so if access is not possible via the shaft, then it would be a case of breaking through the brick wall. About 15 feet beyond that is the original 1930s bulkhead, which was built of concrete - but had an access door built into it. A handwritten note one one map I looked at said the door was "permanently" sealed in 1939 - which might simply mean additional bolts added, or maybe something more significant. It would be interesting to send in a structural survey team to have a look and take photos (and I'll tag along like an excited puppy!). |

There's definitely no obvious evidence in the southbound Northern Line tunnel south of Embankment (though I didn't know about and therefore wasn't looking for evidence of the waterproofed rings!). Even something which is permanently sealed can always be re-opened of course. I would have thought there must be some form of inspection process carried out to this tunnel (particularly as it runs under the District Line and a major road), unless it's been backfilled. As you suggest, I suppose it's not impossible the brick bulkhead wall has been or could be broken through and then made good to facilitate acceess. Would love to know more! |

When you've posted the photos, could you post a link here?

There's nothing that either signalling or civils have drawn that is now redundant, if that helps............ Well... nothing that I can remember appearing on old and mouldy linens. |
