Just looking at the list of these again today.
Copying in Stephen's list from the earlier photo comment of what he believes to be currently active:
090,091,101,102,103,104,105,106 and 107.
DB979124,125,126,128,129,129,130,131,132,133 and 134."
So a few queries:
979017 - no sightings since Eastleigh 2016 - do we assume gone?
979080, 979083, 979085 & 979100 are listed as stored at British Steel Scunthorpe - query whether 979083 listed above is now part of active fleet? Are the others just used within the BS site in internal use?
979114, 979122 & 979123 - last noted at York Klondyke in July 2017 - has this all been cleared now - these wagons gone?
979126 listed as active but no sightings here since Sep 2018
Likewise 979132 - no sightings here since 2016!
Any more info appreciated, thanks
