Last Sunday I had the (expensive) opportunity to visit parts of Euston underground station not open to the public, including the deep level interchange ticket office between the C&SLR and the CCE&HR and tunnels closed to the public since the early 1960s. For the history of these tunnels see here. Apart from the abandoned lift shaft and atmospheric dark tunnels the collage effect of the historic film posters still visible on the tunnel walls was an artistic experience in itself. Some photos I took.
