Once again, I found your video of Killamarsh Station to be fascinating, although I did find my eyes watering just a little, when I realised as to how much this scene has changed since my youth.
So, I have again taken the opportunity of sharing with you, some images taken by myself in “happier times”, i.e. 1977, when this section of the line remained open, as a freight only route in order to serve collieries at Staveley.
For a potted, though relatively detailed description and history of both, the station and the railway, I recommend the Disused Station Website, link below:

I hope that you can relate them back to the remains and locations shown in your video.
