I share some pictures of our current challenge with Helsingør Hornbæk Gilleleje Banen number 4. The project has changed managers multiple times in fifteen years, and the national regulations have changed also in that period. We have also lost some documentation due to the death of earlier managers.
We have made the unfortunate discovery that the profile on one of the axle journals is incorrect. I say "discovery" because the origin of the work is lost to those who have passed. The wheels and axles were turned at the national railway workshops 18 years ago, when they still had a wheel lathe. The workshops and the persons involved are now gone, and unfortunately, also the documentation.
Under current standards, we are required to document the condition of the wheels and axles. We were required to lift the locomotive again and drop the wheels for inspection and measurement. Here we found that one axle was turned with a sharp corner on the journal. Why? We don't know. Supposedly all the work was done by experienced national railway staff, but that is suspect.
So, the point of posting here: any doubt that we need to replace this axle? The axle journal does not have enough material remaining to turn it down enough to return the fillet. The whole situation is extremely frustrating and expensive to correct.
