"Fish Guts" NS 9576 was sitting in the house track at Waddy on Derby Sunday, after suffering from some sort of GE trouble while on 61A the night before. What ever the trouble was, it was bad enough to have to be set out. The airbrake compartment doors were open, but that was just where someone had been in there to cut the brakes out (you can see the dead engine feature is cut in). What you see in there is the KNORR CCB II EPCU (Electro-Pneumatic Control Unit) which is the modern, fancy air brake control valves. All of those modules replace what would have been even more components of the 26L brake (and even MORE on a 24RL or 14 ET or 8 or 6L ) and are much easier to service and replace. You can also see the "Locotrol" (DPU) module, relays to the event recorder ect and so on. I have done a lot of COTS on locomotives over the years, but nothing even close to this hot mess of modern design.
