This section has been "shedding pieces" for a number of years, and the height of the level from the flat cross cut to the rails, over "the collapsed soles", has definitely become reduced, but has it detiorated to a point where it is of imminent collapse?
I am not sure if the main horse level beyond the flat cross cut junction is even still passable?
I have probably not 'done this section ' for about 20 years, and then it necssicitated two flat out crawls.
