One from the US:
"One night he was driving a train when at a long radius curve, he and the Conductor saw another train coming towards them in the distance.
He immediately placed the train into emergency, which is an irrecoverable brake step on the brake controller, and something that they are instructed to do in only the most dire of circumstances.
The Conductor immediately made an emergency broadcast giving their position and the situation in some pretty flowery language, before the both threw themselves to the floor convinced the end was upon them, as the train was still travelling too fast for them to even begin to think of baling out.
The cab filled with light but instead of the inevitable collision, it suddenly went black outside again, the only noise being made by the train braking hard.
In the distance they could hear an agitated Despatcher asking what was going on as there was no other train near them and definitely nothing coming towards them in that area.
Of course the whole episode became a fairly big incident because having braked in emergency, they then had to walk the train from end to end in the middle of nowhere with wolves and coyotes and whatever else walks around at night. The train was over two miles in length so it was sometime before the complete train had been checked, and of course in this time trains were standing along the whole route some hundreds of miles long.
On arrival at destination they were instructed that they were not to work back the next day but were to be driven back for interview with their Manager.
The interview was not initailly pleasant until the Manager was satisfied that they were not trying to cover up something, at which stage it came to light (pardon the pun) that over the years odd reports of a similar nature had come in. In most cases the crews had not had time to respond or make an emergency brake application.
It came to light then that several other crews had experienced this some had reported unusual lights, others had not said anything until this guy posted the story.
Now I can only vouch for the honesty of this guy from the messages exchanged and conversations we had, but I formed an opinion of a good guy, who certainly had the respect of the other members.
Sadly that Forum started to become trolled with heated Union debates and the site owner eventually shut it down which was a shame.
There is another story of a ghostly stop light that occurred in a place called Moonville Tunnel on the old Burlington and Ohio Railroad. After many occurrences of trains making emergency brake applications having seen a lamp stop handsignal, the operator, by then the Chesapeake and Ohio (Chessie), (later to become CSX) installed a lone stop signal on the western end of the tunnel and issued out instructions that no train was to stop unless this permanent signal was showing red. They also forbade track staff to use any other form of light to stop a train.
Here is a link to a website about this. It makes interesting reading.
