Adventures in troubleshooting 6BL brakes. Lots of dead ends and an education through frustration. But we got it eventually. Check out our RUclips for more: / @srmduluth1admin
Always enjoy your updates, I maintain a 6SL equipped loco in New Zealand, and I've had similar issues. A common one is overcharging the brake pipe while the handle is in the 'Running' position, this is usually rectified by lubricating the rotary valve face with a mixture of oil and graphite. We also have a servicing schedule in place to ensure all components of the 6SL system are cleaned and lubricated periodically which is an absolute necessity to keep the brake up to code. Anyway, keep up the great work!
Locomotive technology can be so frustrating. You chase every lead, and they all become dead ends. Then you look at something so simple that's right under your nose that couldn't possibly fix the- Oh hey that worked!
Education by frustration, as you said. Requires re-learning lost shop knowledge, a kind of industrial archeology.
God, there is so much play in the brake piston on that N&W caboose.

I'm glad the old girl will be running soon.
