needs more detailed mapping (steps, handrails, plaque, information etc)

Footpath not visible on imagery, not connected to anything. A visible path crossing the rails is much nearer Via Innovativa but only goes to the S platform. Presumably passengers on the other platform cross at the level crossing.

Suspect this is no longer Romax as they were on Jubilee and are now in Ruddington

Kingsthorpe View & Kildare Close flats have been demolished & land is up for sale by tender. Total area (possibly including more than marked as brownfield is around 5.8 acres (=2. ha).

There's a newish PRoW on the Derby CC dataset from rowmaps continuing track & crossing river here.

This former stable block is also part of the youth hostel, holding family rooms for the most part.
