 In a scene restored to the DVD release, Elwood parks the Bluesmobile  in a tiny Chicago Transit Authority storage shed underneath a bank  of transformers for the CTA trains. Dan Aykroyd (qv) had written  this as part of an elaborate scene showing the Bluesmobile being  "charged up" by the transformers to explain how the car could  perform its impossible stunts. Director John Landis discarded the  complicated explanations, saying, "Its just a magic car!"
