I have posted this request with the Early Rails Grp already but thought I would ask this grp too. I'm interested in "investing" in Hi Tech HO freight car air hoses and would like to know what experiences people have had with them. I would be equipping about 80 pieces of rolling stock so this would be a significant expenditure in resources. They offer 22" and 26" lengths in HO. I presume the 22" is for earlier erasĀ Any info or insights about them would be appreciated. Thanks. Richard
