I shall keep this concise.

Recently a companion and I were exploring the train lines in the early hours of the morning when we encountered the long, dimly lit tunnel that led to the nearest station. The station was clearly visible and the tracks from the end of the tunnel to the station were faintly illuminated, giving us a hazy but reasonable sight of what was ahead of us. Suddenly I thought I saw the figure of a man, but passed it off as a figment of my imagination in the darkness. My friend turned his head unexpectedly and I looked back to the spot where I thought I saw the figure. Walking in the opposite direction was a man who seemed to be clad in black, with dark aviator-style sunglasses, and what I thought was a police officer's hat, that seemed to have some kind of reflective material on it. My initial thought was that he was a security guard of some description and that we were going to be warned against walking on the tracks, but he simply turned his head to face us and walked past.

The next part is slightly less simple to digest.

My friend who is a skeptic and has no great trust in the paranormal uttered "He just disappeared. I can't see him, but it still feels like he is there behind us". I didn't pursue the issue, and we fell silent. The man who had just passed appeared to have vanished into thin air. During the whole incident I do not recall hearing footsteps from him, or any sign that he broke into a run and if he had come from the direction of the station, he surely would have been spotted by staff.

On the way back we ran into another individual, whom I assume was a graffiti artist, but did not match the physical profile of the first.

I don't mean to jump to eccentric conclusions here, but something felt very unreal about those few minutes last night.

I have had a similar experience.
I live in a small town in the UK rich with history. Charles Dickens penned a couple of novels here, and many of our shops have something Dickens related as their name.
I have lived here for about 6 years, and my partners parents live here too.
One day, I was walking to their house. Over the road, I wasn't directly looking at him, I saw a man wearing a top hat, and a cloak. I turned my head to look, because obviously in this day and age, people don't wear such things. We have a Dickens Week festival where people dress in the style of the English Victorian era, but this festival was not on at the time.
Turning to look at the man, he wasn't there. I looked as he was parallel to me from across the road, and he just wasn't there.
I thought rationally, did I see a bin bag stuck to a fence? No, there were no bin bags in sight. Did I see someone else? No, there was no-one else nearby. But I definitely saw a man walking toward the road with a top hat and cloak moving behind him.

I'm looking into time slips right now. As far as I am aware, there have been no murders, or publicly known murders in the area, and suicide by train would not be made known.

I must say, that is an interesting story. If the phenomenon happened as you said, I would love to know what the gentleman was thinking as he unexpectedly lunged into the cruel and alien future.

One thing that caught my attention during my research into this time slip phenomenon is the emotional experience that the individual has.

- Feelings of unease or drop in mood
- Feeling that everything seems unreal or dream-like
- Heightened sense of fear or apprehension

At the beginning of the walk, I could not shake the feeling that "this place feels like a dream", although I have tangible evidence that it was not. My friend was also very apprehensive about entering the tunnel, but this may have been related to his fear that a train may come.

I don't mean to belittle your feelings on the matter but coming from someone who has done a "disappearing act"
semidarkness is a great place to fade out if you are appropriately attired. the real question is what wast such a person doing in tunnel at your location

When I was 10 I got this book - Stranger Than Science by Frank Edwards (1959) . . . I loved that book and need to get another copy.

I, too, read that book as a youngster and remember it fondly. Thanks for reminding me of it again - off to eBay to find another.

As to the OP, quite interesting and thanks for the thread.

I can confirm that the tunnel has no such doors, and only alcoves in which a person could be safe from an oncoming train. It is interesting that you mention the shadow people mythology as I believe I have had quite a few experiences with such an entity throughout my life. I have returned to the place, but things seemed inconclusive. Perhaps I'll wander the area again in the future and take photos.
