Since the classic song "Greased Lightnin" is mostly about how a car will be modified or rebuilt, what would be the locomotive equivalent of this process if it were to be a song? What would be some lyrics for making a Greased Lightnin locomotive or railcar? What locomotive would be rebuilt? (Some examples which I thought of would be PRR 4663 the streamlined doodlebug, CSX SD40-3s, MBTA F40PH-3s, and CP's rebuilt SD70ACUs)
