Amtrak train #4, the eastbound Southwest Chief, is about a mile into its journey to Chicago, IL, as it runs along the west bank of the Los Angeles River on April 3, 2017. The train consists of four (!) P42DC locomotives (Amtrak 16, 200, 137 and 174) and two Siemens SC-44 diesels (SIIX 1402 and 1403) and ten cars (including a deadheaded “Superliner”). The two Siemens “Chargers” are deadheading to the AAR test facility in Colorado, and after testing they will be delivered to the Pacific Northwest to enter service on Amtrak Cascades trains. (And, at that time, the temporary Siemens SIIX reporting marks will change to WDTX.) Two of the four P42DCs will be used to deliver these engines to the AAR facility.
