This is Jane and Ruby walking through a subway ..well it's probably more a little tunnel.
It's not as urban as it seems. It's in our local park....Arnot Hill Park.......the "duck park".....it's actually an old railway cutting that used to run from Arnold / Daybrook into Nottingham. There probably wasn't a subway / bridge when the railway line had steam trains on it. Above the subway is a road and houses.
I converted to monochrome for a bit of urban grittiness
