Thanks, Earl. I see that now. I was having a difficult time tracing the pipes in the photos. So, it looks like a lifting injector on the engineer's side, and non-lifting on the fireman's side. The spec sheet says #40 was built with two lifting injectors. Was it common to replace one with a non-lifting type? Any reason for this? I'm guessing this modification happened soon after the loco arrived on the Uintah. I also wonder about the conversion of the slope back tender, and why making an "extension" was easier or cheaper than making a whole new tender tank.
