If you want to branch out onto the water then how about the Ouse navigation which ends right under the Ouse Valley Viaduct at 1 end and Newhaven harbour at the other. The navigation has never been officially abandoned and there are plenty of interesting things to see. The navigation passes right by Sheffield Park station and through the area known as Barcombe mills. You get a whole new perspective filming from the river. Keep the filming up. Redshirt
