Work has been progressing very slowly here.
My main focus has been working out piping runs up the ends. As built, the WC header tanks were filled from the roof. Later, pipes were fitted to allow rail-level filling. The pipes for this are quite visible, but I’ve been struggling to find how things were handled once the pipes reached roof level.
The obvious thing is they must have been routed to the filler cap along the roof, like most other companies and BR did. Do you think I can locate any images to illustrate this? Of course I can’t! So, some further interweb rummaging ensued.
Several preserved examples show the filler pipes ducking into the body below the end of the roof. This makes a lot of sense, since the roof ends curve down, and making plumbing fit neatly - as well as routing among the passcom gear - would have been messy. I am going to follow this example, as I can’t find anything that shows otherwise, and it will make life so much simpler for construction.
