  1. Great video. I watched it at YouTube and the comments were very good. Even one from a CSX engineer.
    I was wondering what he put in the smoke box through the stack at the start. Apparently it is some kind of air blower to keep smoke out of the cab when the fire is first lit. That is what I gathered from the comments anyway.
    And it was arrow gauge!


    1. Lots of work to get her going! I enjoy this type of video that shows the inner workings. NZ seems to be a beautiful country, too!
