@smd4 posted:Hot, would the Wilson separator be responsible for the massive amount of scale on the skyline casing and boiler near the cab in many of those videos? In one video, it looks like the cab roof is covered in scale!
Yes, that is one of the characteristics of a locomotive equipped with the Wilson system. Union Pacific steam locomotives are a prime example, as they had such "bad water" across the state of Nebraska, and the 800s, 3900s, and 9000s were pretty well covered with mineral deposits from the saturated steam exhausting from the circular separator of the Wilson system. Not being a SPF, I'm not that familiar with how many classes of steam locomotives the PRR had equipped with the Wilson system.
