The first script ever turned into a TV show by the legendary David Milch as referenced in his memoir. This could only happen because there was a writers strike at that time and he was not part of the Writers Guild.
The introductory scene shows a Regional Transportation Authority Highliner train pushed by a General Motors EMD F40PH locomotive passing the then-headquarters of Cassidy Tire and Service on its arrival into the Chicago and North Western Terminal in downtown Chicago, Illinois. The seven-car train sports a mixture of their original C&NW green/yellow and subsequent RTA red/blue-striped color schemes.
