Rick and Chris thanks for your input and pictures. I just felt certain that that locomotive, and her sisters, had to have that job done for inspection purposes at some point , on a regular basis. I just thought that with the nose piece shrouding that it might have been hinged, or something.
I remember as a kid watching the old blacksmiths at the K&I Roundhouse, installing a new exhaust nozzle in the front end, and they had just finished doing one of those wash jobs. I also saw this being done at some point in time, around every roundhouse in Louisville, and was done very close to their ash pit operation!
Figuring they dump the fire, and clean the ash pan, then move on, and open the front door, then brush the tube sheet out. I only remember seeing that done one time, but that was just probably the time that I showed up, and also keeping an eye out for the Railroad Detectives. They were easy to spot, as they all dressed like Broadrick Crawford......
Chris I believe to do date, this is the best post than I've been privey to read since being a forum member, and there have been a lot of great, great posts!.....Brandy!
