I have been fascinated by so many of the topics on your blog, especially those of a subterranean nature. London is fascinating underground and theree is so much of it, I doubt if has all been documented.

What I’m writing to you about is the snippet you posted on the Waterloo & Whitehall Railway. Many years ago whilst serving in the military, I spoke with someone who told mehad by special invitation been taken down into the Met Pols ‘Black Museaum’. This would have been when the Met were at their former headquarters, close to Portcullis House. He related to me of seeing either the entrance, or part of an entrance to a tunnel leading under the river. He went on to say that no one went in there as it was flooded. Sadly, this is all I know and all he ever told me. His visit would have been before 1963(ish).

About 12 years ago I read a small article in the Questions & Answers column which the Daily Mail use to publish every Saturday (I believe). Someone had asked about this railway and a reply stated that there may still be a loco and carried still abandoned within the long disused tunnel.

Personally, I really don’t know, though I am an extremely keen railway enthusiast. I wonder if it would be possible to plot the precise line of this railway beneath the Thames at then see at which point it reached dry land on the northern bank.

Obviously the Old ‘New Scotland Yard’ building must have changed and been altered considerably now that the MetPol have long left. I would imagine it has been seriously refurbish inside and within its basements to accommodate the new parliamentry offices etc.

I’m enjoying your blog website and photographs very much indeed Ian and am slowly perusing the contents with great interest. Both you and I seem to have a great deal in common. London is a fascinating place to explor both above and below its streets and rivers. I’m sad I not longer live nearer to it. I grew up in Wembley and Harrow and now live in Huntingdonshire.

My best wishes and kind regards to you from
