37688 Great Rocks & D6817 (37521) pass Culham on 24 May 2022 with the 1Z68 07:26 Weymouth Jersey Siding to Crewe private charter. The massive net above the railway is in connection with work taking place on the 400kV power lines that cross the line here. Just off to the right, and also in connection with the works, an automated proximity detector alarm was giving out a trespass warning every time someone walked along the adjacent public footpath!
