| This 3-2 
                heavyweight business car is painted green with black band and 
                yellow lettering and runs on 6-wheel passenger trucks. As older 
                observation cars were converted to business cars for executive 
                use, they were also given an exterior upgrade with new siding 
                and thermally superior windows. The changes made them look like 
                the newer, light weight passenger cars allowing them to blend 
                in with newer fleets. |
