Surreal. Wonder what they do with all the removed segments; presumably there isnt much of a need for spares! Would they have a use in station reconstruction projects I wonder.
Given that the removed rings are over 90 years old they certainly won't be re-used in their current form although they can theoretically be melted down to form part of the newer spheroidal graphite iron rings which was pioneered in 1943 and has been used recently on tunnel the works from Baker Street to Bond Street on the Jubilee. The papers published by TfL just refer to disposals.

It blows my mind that even with modern technology, this stuff can be done. The precision needed must be hard enough above ground, let alone underground in clay! And to think the Camden Town junctions were built around the working railway with minimum disruption and none of the technology we have now. Just absolutely amazing.
