Love the videos Roger, and the air conditioners. I think my Illinois Terminal set in the 90's (yes, in my "history" the IT never went bankrupt, and rather through mergers and acquisitions, between 1980 and 1990, became a Class 1 railroad), should put a couple of those on their caboose. Great idea...again.
Nice video. I know rule #1, it's your layout. But I'm curious to why you have shown rolling stock and features such as modern roof top AC on cabooses, all of which are things after 2000s being you stated you model the 80s. Like your thoughts and ways for that industry.
Thanks. I do have some anomalies but he AGW leads the industry in innovation. The AC on the cabooses are because they are mobile offices. The local crews use them instead of a fixed office building which we would have to pay property taxes on.
