Dirty Mary, Crazy Larry

NASCAR hopefuls, driver Larry Rayder and his mechanic Deke Sommers, successfully execute a supermarket heist to finance their jump into big-time auto racing. The unorthodox sheriff, Captain Everett Franklin, obsessively pursues the trio in a dragnet. The trio evades several Dodge Polara patrol cars, a specially-prepared high-performance police interceptor, and even Captain Franklin himself in a Bell JetRanger helicopter. They meet their doom when they randomly collide with a freight train pulled by an Alco S1 locomotive.
