When CSX started, it began with a blue and gray paint scheme, dark and simple. I heard the Yellow nose, end and side frames were to reduce grade crossing incedents. The yellow front did make for a brighter scheme, thus bright future. Ironically, around the same time CSX adopted this scheme, Dodge had bought AMC for the Jeep brand. in 1987-88 Jeep introduced a Wrangler with a polished stainless steel grill. It was advertised in dealer and customer litrature as "Bright Future."
