For there to be more visits to underground sites, there needs to be more people organising them.
Get in touch if you can help.

Unearthing Innovation: 200 years of Tunnelling from the Brunels’ Thames Tunnel to the Elizabeth Line - Brunel Museum Now carrying over 800,000 passengers a day, London’s Elizabeth line presented a series of challenges for engineers as they upgraded 30 stations and built 10 new ones, all while keeping the city moving. None of this would have been possible without the modern descendants of the Brunels’ early tunnelling machines. Help us mark the 183rd …

Close-up of the end and ~3 metres of a new Piccadilly Line “2024 Tube Stock” train on platform 2 at Acton Town Station. Car is labelled 38030 Wide angle from the other end of the train, showing the front and maybe half the length snaking down the platform. There’s a high-vized staff member leaning through the door. Car is labelled 48030 Drone photo from the south, showing the train in the platform. (I am a professional drone operator and do not recommend you fly your drone around any railway infrastructure.) Close up through tube door window showing “do not lean on door” signs.

I went on a hunt for the new Piccadilly Line tube trains yesterday.

I'd seen that they were testing them around Acton Town on Saturday, so headed over there to see if I could see one, and I struck the jackpot! There was one waiting in a siding, then another came round the corner into the platform!

I caught up with it at Hammersmith, saw two units out on test trundling up and down the line. Official TfL line is that the trains will enter service in the second half of 2026.

AI generated spoof movie poster entitled Tunstall Has Fallen featuring Gerard Butler in ROC uniform (with incorrect badge) and the tettering cliff top building.

Sea erosion has caused the Royal Observer Corp post at Tunstall to fall down on the beach.
It's been the biggest cliffhanger since a sister post at Aldborough met a similar fate.
