Early Conrail wide-cab action, as a big GE smokes it up with an eastbound manifest at 4th Street. The building on the right housed the shop offices of GE Environmental Systems, formerly the Union Boiler Works of the Buell Emission Control Division of Envirotech Corporation. The chief product of Buell/GE was oil refinery cyclones, a major component of fluid catalytic cracker units, where crude oil is transformed into lighter products, such as gasoline or diesel fuel. Cyclones collect and recycle the all-important zeolite catalyst, which carries the large crude oil molecules through the process. The shop building was built in the first decade of the twentieth century; the last cyclone left the shop complex in 1997. No. 6093 was built by GE Transportation Systems in June of 1990.
