I like the Waterloo and City line, all the other tube lines are a bit too 'unnatural' in my mind, I need to see dust covered tunnel walls or excavations through solid rock to feel that I'm really underground ::) 😞 :lol:

Post Office underground railway.

I thought that was abandoned?

Under maintenance pending adoption as a tourist venue.

Also heading for London. primarily to National Record Office at Kew.
Imperial War Museum closed for rebuild, Kew Bridge Steam Museum closed until 24th March. Might get into other pumping museums but most are by appointment only at this time of year.
Try Bunel Museum at Rotherhide, cheap entry& open 7 days a week. Not been there before but definetly going, worth a look. Greenwich Maritime Museum free. Try London Transport Museum which is at Covent Garden. Science Museum down engineering side, have a Cornish beam engine, or did many years ago, also great models of Doxford Marine engines (which I worked on).

Drive up, You will struggle by train!! :thumbsup: :thumbsup: :thumbsup:

Many of those are cut and cover. Its only a few of the central London lines are truly tunnels

Are the Camden horse tunnels accessible, or has the whole area been made over?

Something I'd like to do one day is trace some of the "lost" rivers of London. There are a couple of excellent books on the subject showing clues like the remains of arches built into walls and the like.

aye like in Paris the first were cut and cover, like the central and district, hammersmith? I can't remember. I have a mate in Russia who somehow got permission to go down the Helsinki and Moscow metro systems, his photos are amazing, I'm going to try and ask permission to photograph the Helsinki one when I go in August 🙂

Thanks for the suggestions.

In the end I plumped for the Science Museum (again). I just can't resist having an Atmospheric engine, several Boulton & Watt engines and one of Trevithick's engines within yards of each other. The display of 18th century scientific instruments is very impressive. Possibly my favourite exhibit is a small case which most people walked past which contained a 1790s model by Trevithick and Watt's model of the separate condenser.

I also visited the Museum of London - I remembered seeing a Time Team(????) documentary a few years ago about the excavation from a well of a Roman bucket lift which intrigued me at the time. The remains of the bucket lift were on display unfortunately with no real interpretation which I found rather disappointing. That said the rest of the museum was excellent.

Not mining related in any way was the Old Operating Theatre which was Mrs Tamarmole's choice - highly recommended.

A great visit - but I am more than happy to be back in the Tamar valley.

As Morrisman said, the Kew Bridge Steam Museum is certainly worth a visit on days when it is in steam. The Abbey Mills Pumping Station at Stratford is also a good bet. The pumps raised the sewage in the London sewerage system between the two Low Level Sewers and the Northern Outfall Sewer, which was built in the 1860s. The Bazalgette sewerage system would be a great visit, but I don't think its that easy to get an invite. I wrote a dissertation on the New River many years ago now, which was the first purpose built water supply system bringing water from the River Lea near Ware in Hertfordshire to New River Head at Clerkenwell. There are a lot of pumping stations along the route and the stump of Smeaton's wind pump still remains at New River Head. Worth a walk.

An archaeologist friend of mine has pointed out that there is a working replica of the bucket lift at the Cranborne ancient Technology Centre in Dorset.
