Hello, kind of new here but have a nagging question for some of you folks with larger steamers. I was going through some of my old magazines and read an MR article about a O scale club in Denver, and it was a 2 rail layout. I remember vividly a picture showing a Rio Grande L-105 challenger, and in the text the article stated twice that this engine weighed 25 lbs. That figure always impressed me. After I got into 3 rail O gauge, I picked up a few older scale articulateds, a MTH Proto 1 N&W 2-6-6-4, C&O 2-6-6-6, and a Williams brass cab forward. The MTH engines are a little over 16 lbs and the Williams seems just a little lighter. I have heard that the Lionel Big Boys weigh in at 20 lbs, but this is still 5lbs lighter that that L-105, which is a smaller engine. I still can't figure it out, unless they added weight to make it pull better? I couldn't imagine any sound equipment adding to the weight, as this article was from the late 80's.
I know most people here probably don't weigh their engines, but I was curious if anyone has ever seen any other O gauge steamers that break the twenty pound mark? Sorry to start out with such a crazy question, but its been bugging me ever since I read that article. Thank you.
