Re the Nimbus story....the feedback that I'm getting is that the story was written as a fictional Christmas ghost story by some members of one of the Deltic societies.

As we all know, there were just 23 Actual Deltics built, while according to one Railway magazine back in the 1970's/1980's and Not sure of actual title right now, claimed there were over 100 made, by numbering one 55 1?? and NO joke.
