Slightly sad news there. Access to the Hackworth et al works buildings, cottages etc. is necessarily restricted until restoration is completed; target date of 2025 if I understand the situation correctly. Still good to visit the collection, but I did like the 'early railway' evidence: "Here's my house, and if we just cross these tracks, that's where I build the locos and wagons". Wonderfully evocative of the beginnings...
