Stromschiene
The yards passed into British Railways ownership in 1948, and in 1960 a new freight depot opened south of St Mildreds Road, handling at its peak over two million tonnes a year of continental fruit and vegetables. However, following the decline of rail freight the St Mildreds site was developed to become the Up side Electric Multiple Unit stabling roads of Grove Park depot. All roads provide Third rail 750 volt DC traction current. The Southeastern Safety Training Centre was also built here.
