I finally managed to get inside the famed Thames Tunnel today, having just missed out on the last set of rare tours in 2008. As perhaps the most ambitious engineering project of the Victorian era, it has fascinated me for years, and I've written about it in each of my books.
I visited the converted former entrance shaft in 2012, but this time got to walk through the tunnel itself, thanks to engineering work and a weekend of tours arranged by the London Transport Museum. Ironically, the engineering work that enabled the tours also made getting there harder, but it was worth the extra trek. Tickets sold out fast (much like they do for Aldwych tours), but I managed to get some for myself and Mrs P. It also happened to be my birthday, making for quite the present.
Here's a selection of photos from the tour. For those who couldn't make it, don't forget that you can catch a glimpse of the tunnel from the platforms at Wapping and Rotherhithe Overground stations, and even ride through it on trains between the two. For those unfamiliar with the tunnel's history, see here.
