From the Guardian, an interesting project – the Tashkent metro ….

After the ban on photographing the Tashkent metro in Uzbekistan was lifted this summer, Amos Chapple, RFE/RL’s photographer went underground to reveal the art, architecture and nuclear-blast protection in Central Asia’s oldest subway system.

Some wonderful stations here…

And a less challenging project from Simon.  A remaining semaphore signal on Britain’s railways.  Can’t be that many left?
